Need help ASAP... flexplate just barely clears..can i still use it??

Okay heres the deal...just installed the engine and tranny. Nothing is hooked up yet. Anyway the old engine had a 1 piece rear seal so i knew i couldn't use the flexplate on the newer engine (2 piece seal). I used the wheel that came with the engine... Now that its in it JUST barely clears the bellhousing on the 700-r4. this wheel is about an inch bigger than the old one. I thought that was the difference between the 2 kind...but now i don't think so..
Anyway will this flexplate work since theres only about enough room to put a finish nail between the wheel and the bell housing? I know that my new starter is for this flywheel so if i end up getting a differnt size will this starter work?

Please help me! i'm fearing having to pull this apart again

Sounds like your new flex plate is the 168-tooth version, while your old one was 153-tooth.

The larger one will work; however, you'll need the other starter (the one you say you have, for the larger flex plate), and you'll probably have to enlarge the hole for it in the torque converter dust shield. Plus, since the starter will move out away from the block by about 1", it may interfere with headers. So you may want to come up with the smaller flex plate anyway.

I agree. Do it right the first time while you still have the option. You''l kick yourself later for not fixing it now. Get the proper size flexplate and use the existing starter.

The smaller flexplates for the two piece cranks are so common, you might trip over one when you enter a junkyard. They came on a lot of the two piece 305's in the mid to late seventies cars. Should be a piece of cake to locate one!
