OK so i just bought a TH 350 for my 99 Z28 A4 and i need a little info. Ive read all the stickys and all the posts but most of my questions have not been answered. I read that i will need to get a a flexplate out of a 98 LS, but i dont know why. Why cant i use mine? Im not sure on the tranny lines either. Also, the crossmember. why do i have to get a new one? Can i not just modify the stock one? What about the TA? I dont see why its necessary to spend 250 dollars on a relocation kit. im not to worried about not having a speedo but if i choose to use it what can i do with the 350 tailshaft. ive read that i need some sort of adapter. what do i need and where can i get it? I think thats all the questions that i have for now. but let me know on whatever you can. thanks

My flexplate is from a 99 and it works. As for the crossmember, its just easier to bite the bullet and get one made. I got the bmr one that relocates the torque arm and its really an outstanding product. Well worth the price.

so you didnt have to get some sort of spacer for the convertor?

If you dont order a torque converter (th350)made for an ls1 you will need a pilot spacer, but thats it.

the 98 flexplate is a dual bolt pattern flexplate, it can bolt up to ls1 converters and sbc converters. If your running a sbc converter than you will need it along with a pilot spacer(hays sells one). You can modify your crossmember to work you just need to bring it forward and down a few inches. You will have to lack the two tranny next to eachother to see how much. For the torque arm you can buy a tailshaft that has the provision for a torque arm on it.

Or save yourself a headache and buy the BMR crossmember.
