Hey Guys, I have a 86 Mazda RX7 that im putting together a LM4/wc-T5 combo. I bought a 3899621 bellhousing to mate up the T5 to the motor. The trans is a from a 99 V6 Camaro. I heard it was one of the best choices. Problem now is that the bellhousing is not bolting up to the trans like I heard it would. Did I miss something? Or is there another piece that goes in-between? I'm a little confused.

Yes, you need an adapter plate, let me find a thread about it.

I found this http://transmission.moderndriveline....late-7p222.htm
I emailed the company and they came back to me saying this would be the part I would need. Its great they got back to me so fast. I guess now starts the nickel-and-diming part of the build/gathering parts. Figuring out what works.

May be a great solution for a Mustang T5. (I may try that later)

Is built for the Gen4 T5 and puts the trans straight up. Verified to work.

I bet either would work fine though.

I talked them as well, they said they have one that is straight up and down, that doesn't have the 7degree rotation.

Hmmm...I wonder if its similar to the above one and what the price difference is?

Another piece to the puzzle, what do I do about the throwout bearing? Ive read to keep it hydraulic and to upgrade to a bigger 7/8" or 1" bore master cylinder. Can I use the factory throwout and just open up the hole on the side of the bell a little bigger?

I know its been a little while, but I thought Id give a little update. I finally got an adapter. I went with the Modern Driveline unit: http://transmission.moderndriveline....late-7p222.htm
It was a little cheaper and had another mounting bolt for the Bell part. So that made me feel a little more trusting in it. I have temporarily mounted it all together. Looks like its going to be great. I dont really like the 7* rotation deal, but maybe it'll actually improve the ergonomics. Still have a long way to go with this build, but glad to have one big/important piece of the puzzle acquired.
