And what do you guys do with the plastic inner wheelwells in the front? Leave them or remove?

Take them out, they are just one more thing that can burn. They serve no purpose for derbys.

You guys do anything with the front fenders? Box them out on the inside? Or run them the way they are?

Which is the easiest way of telling which trans I have in the car? It says Metric Hydromatic on the trans pan?

My Oldsmobile had a transmission that had that pan, and it was on a Turbo 200c, which will work for derby use, but it is not desireable by any means.

I looked at a parts-store website to see the shape of the transmission pan gaskets. I believe the 700R has a flat pan, the 350/400 (?) has a flat pan with one corner 45'd, and then the others I didn't pay much attention to. All of mine have been 700R4 transmissions.

I'm a newb, helping a buddy build a '77 caprice wagon. Our rules are pretty strict, so I'm trying to see what we can do to keep the back end of this thing from going down. I've seen a couple of picture of the frame notches, but I'm trying to determine the location of the notches. I'm also looking for suggestions on how to pre bend this thing. It's already sitting kind of low in the rear also, I'm thinking the coils have gotten weak, any ideas there? Leafing is not allowed here. Thanks for the help.

My rules are strict also and state no notching so I dimpled my frame right after the wheel hump in and then again about 12-18 inches from the bumper mount right under the foot well for the rear seat. for the springs I took out the old ones and replaced them with the front springs from a mid 80" g-body car (we used to race hobbys so I have a lot of them). They are tall, stiff and just barely fit with the stock shocks and seem to jack up the rear a bunch. To pre bend I put it on the trailer and chained it down tight at the rear dimples and then used a porta power to jack up from the rear shock mounts and bent the frame up. This is the first time I have run a wagon so I hope that it is enough. Attachments:

I have also been told to bend the body at the gas filler door by putting a jack in the window and jacking up the roof and the fender down on both sides. I cannot do this because of my rules but it looks and sounds like a good idea. I might just beat the tar out of mine with a sledge after tech.

It says nothing about not prebending if u notch and set the rear high bend the quarts in and roof up u should be good to go higher the better with these cars

I have been told that even with the notches on 80s GM cars, you must still be smart with your hits to start them bending in right direction. I had Cadillac that bent up like it should have but because of a flat tire and a hard hit, it bent up which shoved the bottom of the rear hump inward as well. Depends on your luck and how you manage your hits, but I think those above dimples look sufficient enough. I have my notches cut about that big. I have done my notches about 6'' in and then 2-3'' in front of those. Make sure you cut the stiffening ribs built into the body floor.

Do you guys crease the whole rear quarter? Or just the top half, say from the wheel well up?

on the bubble buick wagons has anyone ever cut a pie slice out of the rear frame rails like a notch and jacked it up and rewelded it. if you did,did you have good luck with it or did u weld it and then double dimple it. this is my first wagon and i am kind of curious to see if it works out. thank you for all your help.

Some places won't allow you to re-weld it. However, I have known someone who did the V notch with a square notch in front of it and it rolled up very nicely.
