| I am new to the sport and alot of ppl on here say to collapse your bumper shocks. So what im wondering is how do I go about doing this...Im running an 86 caprice classic wagon? Please explain thuroughly as I am not overly mechanically inclined but am learning. |

Drill small holes in the sides or bottom of the shock mount, as close to the bumper as possible. Then start pounding in the bumper with a sledge. The fluid will go everywhere-much farther than you think. I recommend placing a towel over the hole before you start hitting.
Don't do what I did on my first one. I didn't drill and started pounding. Shock went in a tiny bit and stopped. THEN I drilled and MAN did that stuff spew.
Also, after both mounts are drilled, don't try to pound one shock in and then the other. Do them a little at a time, alternating. Otherwise you could kink it and it won't move.
By the way, the shocks will ooze fluid for weeks |

| Much easier to do without the bumper on it. You should be swapping bumpers anyways. Then you can do one shock at a time. |

| So the car I got hit a tree with the front end, so i already have the bumper off and plan on putting a different one on it, however the bumper shock on the passenger side is almost already all the way pushed in from the tree. Does this mean im gonna have major spewage when I drill it? |

If it's halfway in, the impact might have blew out the internal valve, so I think you might be OK. But be prepared!! You never know.
Derbyman, thanks for pointing that out. It would have been easier for me had I NOT put on my new bumper first |

I remember once we were heating a bumper shock up with a hole drilled in
top to try to straighten a bumper that was bent down on a 76 gran fury.
We had a backhoe shaking the rear of the car off the ground while we
tried to heat the bumper enough to get it tweaked.All of a sudden it
started spouting boiling oil on fire and raining fire everywhere.
It was freaky and everyone ran like hell cause that stuff hurt.j

First time I did it, I was using a torch to blow a hole. Kinda, ya know, looking closly and intently at the metal heating up and starting to pool up. Then WHOOSH, looked like ol' faithful, but with fire. I'm just glad I got great reflexes, and reaction to move out the way. Years of martial arts paid off. |

| I did the same thing, but I was welding a bumper shock on an 80s Chrysler for MJ Fairfield for the first Yorktown show, burned the hell out of my hand and arm... didn't slow me down though. Those guys there thought I was crazy to shake it off and keep welding. |

| They are filled with like a white plastic crap... no I hardnose all mine and weld them solid to the end of the frame. So there is no need to collapse them. |

A little tip, when drilling out the shocks. Take a cap off a spray can. Drill a hole, in the center. Then put it on the bit, top towards drill. Do your drilling of the shock. If you get a gusher, the cap should catch most of it, instead of you and your cloths. Wear some goggles, just in case.

| If you have the bumper off, could you just use a sawzall and cut the back of the shock off? I think I'm going to try that this year, unless somebody tells me a horor story. |

correct me if im wrong, but drill the holes with a cordless drill out in the woods or a part of your lawn ya dont care about....JUMP in the car(dont get hurt jumping, I know some of you guys are getting old) Fire it up....throw it in drive....size up that big ole oak tree and give her a good SHOVE right in the center, for the most part both sides should go in fairly straight. WHILE parked on the tree.....you could prolly bring torches and brazing rod and just give it a quick lil braze to hold ya till your back at the garage, then weld her solid RIGHT?

| Gfalls......Thats hard on trees man. Take the bumper off, drill 1 hole on the bottom of shock and 1 on top.(for a vent) Take a sledgehammer and beat the bumper mount plate in till the shock is compressed all the way. If all the fluid is out, it won't come back out. Weld solid. Same to other side. Weld new bumper back on. Done. You'll save a few trees in the process. |

| you can weld the shock itself you just can't weld it to the frame we have some crazy rules here you can weld the doors but no seem welding and you can only run the stock springs on the car like leafs on leaf spring cars coil on coil spring cars, you can weld only a little of the trunk you have to use stock type bumper mounts like if it had shock bumpers you have to run shock bumpers if it had steel mounts you have to use steel mounts |

You mean how to keep the whole bumper from falling off? You can buy "no weld" bumper mounts. Or chain/wire the bumper to the frame and I always run 2-4 places for wire running from radiator support to the bumper. If the mounts break, the wire keeps it on the car. I have a real good cheat to where they WON'T come off. You don't have to weld em either. (but it helps) |

| Ok, here's my little cheat. (I'm in the mood to ramble) If your using the shocks that go into the ends of the frame, (77+ gm's) Take it all of. Bumper, shocks, mounts. Cut a hole in the ends of the shocks. Run a piece of 1 inch allthread from the back of the shock,(inside the frame) thru the shock, thru the back of the steel bumper. Use thick plates, then nut it. Throw some dirt and mud on the nut inside the bumper so tech can't see it. All the original pieces will hide the allthread. The bumper WILL NOT come off. Replace all the bumper mount bolts with new grade 8 bolts. |

| Country boy style we use the torch to burn a little hole in the bottom of GM's.The oil burns but we're out on the farm and it don't hurt nothing on the gravel driveway.then BFH each end equally and burn 3-4 rods all the way around.Tough part is welding real solid but being able to get it off to reuse that high dollar 74 bumper on something else later. |

| I just took the torch to them. You don't want to get the oil on you because it will burn. |

Hard nosing a car is a term used when you weld your front bumper straight to the frame of the car. |

Weld all the seams on the body and the frame. Weld the hood seams. Bolt the hood down with as many as you can. If you can't weld the bumper pieces together, then use gr.8 bolt, nuts and bigger washers to put it together. Same with the bolts you mount the bumper to the shocks or frame. You could also weld steel strap to the top and bottom of the frame. If you're allowed #9 wire, use as much as you can. Weld washers to the car, where the wire goes thru.
Those are some things, that lots of derbys allow. Make sure what you can do, or get away with.

Pretty much what I said above, will also work for you. But also ask this in the Chrysler thread. You should get more ideas there.
