Who makes the flanges for converting a C2 crossmember to removable.
Thanks in advance.

Joe, a link to that supplier is in your other thread, referenced in one of my posts. Sorry I haven't posted photos yet, life keeps me busy.

I gotta go eat dinner but I'll look for the info, Gary

Here are some pics...

Flange welded on end of fixed x-member. Had to rework top contour of flange to clear floor. Now has about 1/8" clearance
and only 3 bolts, had 4. Wasn't happy, but I was committed.

X-member. Weld around inside gives 360 deg of attatchment. Not possible with outside weld.


Shot to see clearance, hard to see.

Made my own.

I believe I prefer your version, should have more clearance between bottom of body and top of crossmember flange. Does it?

Here are some pics of what some previous owner (BUBBA) did to my crossmember many years ago and my more recent efforts

Its a long way from perfect, but its the best I could come up with - with the body still on the frame.

Looking at the plates or channel solutions for making the crossmember removable, I think the plate design of the previous poster looks neater and appears to be more secure? I contemplated plates myself, but dont have a lift or a welding machine to make that a feasible home fix.

Thank you Troutster, 66, Jofa;

Especially good pictures. And thanks for the link Troutster.

I have to crawl underneath and see what the clearance is before I buy or make my own flanges.

66 Vette

It has plenty of clearance. All of the fabrication was done with the Muncie transmission still in the car. The pictures where taken after I removed the Muncie transmission and before I installed the SS700.

How thick are the flanges?

66 Vette

All are 1/4" thick.

Thanks!

66 Vette,

How did you cut the crossmember?

Why wouldn't you just install a C-3 automatic cross member? Just curious.

A saws-all easily cuts the cross member.

I have welded in the flanges for my buddies; however, several of our gang have gone to the channel iron with bolts. I think that is easier.

One friend cut his at V angles and has an internal square tubing with bolt which a really strong, clean look.

I'm cutting mine with a sawz-all on Friday.

I cut mine with a sawz-all.

The first version I had was just like everyone else..Imade flanges for stock crossmember. Worked great except I had 3" pipes at the time and there were some awful sharp bends off the big block headers to get through it.

Later I had a local roundy rounder shop bend a piece of tubing and I added flanges to it and built a trans mount as well as transferred the parking brake roller to it. Now the pipes can come straight off the headers with no twists as they pass under the crossmember.

They were cut with a saws-all.

Thanks.
Any tips you can give about the cutting? Make entire cut with saw parallel to floorboards, or 2 separate cuts? Are you able to cut entirely through or do you have to twist/break off the last bit of steel?

That is one thing that concerns me, I can't cut anything straight. Trying to think of a way that I could get a square cut. That matters most if you are going with the flanges on the ends. If you go with the overlaping channel approach, then it is much less important I think.

But, then what do I know...
