Post Need help with switch trannys please

Hi, Ive got a 1984 Z28, it came stock with a 700R4 automatic. I put a 350ci replacing the 305, and also a Th350 (with b&M shift kit). The problem that i have ran into, is after i put the tranny and motor in the car...There is a piece that bolts on the bottom of the tranny, with a peice of uber and 1 bolt going straight down (this goes through the Crossmember), Well with this new tranny the hole in the crossmember and that bolt dont line up, the bolt it about 2-3 inches toward the front of the car to far, Do i need a new crossmember, or could i drill holes and mount the Crossmember foward(car is a unibody so i didnt know) or could i just put a steel plate in there? SOrry if this didnt make sense, just took some exams yesterday, my brain is fried, Thanks all!

If it`s worth doing it`s worth doing right. Call a tranny shop, they`ll tell you exactly what you need.

stick with the 700' less trouble to fit the car you can adapt 350 into this car but doing it right can cost more than keeping what you started with. unless you good at makes brackets for torq bar for rear end. early vega, monza 250& 350 trans tail housing can be used with some modes makes a toung for trans mount all this isnt emission legal in Texas ck with your state if you plan to run this on the street.

You have the right ideal. The TH350 is about 2 3/4" shorter than the 700R4 so you have to move your cross member foreward to receive the tranny mount. You probably need the same type mount that was on the 700 and it should bolt up to the 350. Also, you will need a new drive shaft made up 2 3/4" longer than the one you removed. Make sure your 700 yoke wil fit the 350 (it should) and take your old drive shaft to a drive line company and tell them how much longer you want it and they should make a new one wity your yokes, new ujoints and balanced for less than $100. By the way, your frame just might have the holes drilled to move your cross member if the Th 350 was an option in 84 Cs.
