Looking to see what you have done for a cross member.

Before I put the 4-speed in my 50, I had a 2004r behind my 348. I removed most of the original frame bracing except where the brake master cylinder mounts up.
I then bought a 4 inch drop tubular universal trans cross member from speedway motors and also got the top-hat style ends got it. Then it's pretty much cut to length and weld it up then bolt it in.

Hi Z28. I do my own but use a design that is very similar to the Walton's product.

Because they loop over the tail and have a dropout section underneath they give you both strength and remove ability.
When you take out the original member you remove a lot from the original frame, given you almost always do this to put more power through it I believe it is very important to replace that strength and reinforce it to the rear.

Hence I would recommend that you also fit a rear shock cross member to help support the rear frame. Walton's also make these. Theirs are bolt in as the frames vary a bit, but there is nothing to stop you bolting them in then running a couple of supporting beads.

If you had an Oldsmobile it would already have this member.

Cheers Kiwi.

ps. When doing a trans member always remember your car will have an exhaust system, and if it's real low it will potentially need to go over or through the trans member.

KZ,
So the 4 inch was the correct amount of drop?

When you mentioned the top-hat style ends, are referring to the ends that come in with the 55-57 cross member kit?

Thanks,

This is the Walton Mfg. crossmember. The trans is a 700R4.

When In installed the Muncie over 50yrs ago, I went with the KISS principle (Keep It Simple stupid) it simple. I used a 55-57 style bell housing, had brackets welded to the frame for stock 55-57 bell housing mounts, retained bone stock 51 Chevy clutch linkage, cut the center our of the stock transmission cross member and then sandwiched it back in with steel plates.

Oh ya, and my warped philosophy regarding auto trannys----------------"T hey should all be thrown in the river"!

Hi DZ, there isn't one right answer. But I am sure you would consider the Walton method if you had to do another one.
That to me is the beauty of these forums. We continually get to look at and see other ways of doing things and the answers just keep getting better.

As I have said many times I would use Walton's stuff if the freight wasn't so prohibitive.
There is also another aftermarket style where you slip one tube inside the other to deal with the width variances of frames.
Requires a full circumferential weld all round each end.

Easy with the body off, but not everybody is going that direction.

Cheers Kiwi

I would have to do some trimming and modification in order to get the the Walton 7004r one to fit the 2004r. I'm not against doing this, but I if can find a decent one without the need to hack into it I may go that way.

What did you do about the parking brake linkage?
