Will GM 200r4 work with factory floor shift location?

Treblig, I like the idea of adding more rigidity in that area, but I am no mechanical engineer. I would like to add a short triangulated bar to the front of the subframe connectors to original torsion bar crossmember, but there's not a lot of room there unless I just use just a triangle piece of flat plate and weld it to the inside, bottom at the intersection of the subframe connectors and the factory crossmember.

For crossmember add-ons, I've always liked the look of the round tube type crossmember with the mandrel bends for the drop down at the trans mount with a flat tab to mount the rear trans mount, but I don't have the technology for that at home. I guess if I found a race care fab shop in my area the could make me up one, but this isn't LA.

Which rear mount did you use? I was a bit confused when I started looking at the Chevy parts on Summit. They didn't list a 200R4 mount, but just about every other one.


You know that's something I totally forgot to post. I had to do a little research but as it turns out the trans mounts (GM) are a dime a dozen and available at any parts store. Just don't screw up like me and accidently grab the wrong nut and strip the threads on the bottom stud. The whole tranny is METRIC and so are the 2 bolts that hold the mount to the tranny and the one nut on the bottom that holds the mount to the cross member. I had so many nuts and bolts laying all over the car lift that I accidently grabbed the wrong one (SAE) and since I had bought a lock nut for the mount so I didn't think much about it when it went on a little tight. Well I was wrong again (that's the second time in my life I've been wrong!!!!LOL). Anyway, it stripped the threads off once it hit bottom and I had to buy another mount. But they are cheap and plentiful so no big deal.


Please ignore the "China" reference on the box top and remember....METRIC, METRIC, METRIC!!!


As for the triangular brace, I've read that other members do exactly that on the front and back of the cross member. helps to stiffen the sub frame.
