C4 help

Hello fellow fox nutz...

I have two C4's.  I have 1979 from a fairmont rebuilt to 450hp 3 years ago.  Worked well behind my 2.3T.  I keep the original v8 bellhousing and a 2000 stall 12" rebuilt cheapo torque converter from the 79 C4.

Last year I got a 1978 C4 from a mustang II 302 setup, rebuilt upgraded and with RMVB.  This one is supposed to be stronger than my 79 tranny, better parts. With the super small BH, flexplate, spacer and little 9" torque converter.  I didn't realize that ford made this super small C4 bell housing.  So this has caused me problems.

Anyways I finally got all the different sizes figured out.  That 302 BH that I got with my original fairmont tranny is the big 164tooth.  So I used that cheap torque convertor, AOD spacer, new 28oz flexplate.  Bolted in perfect.  With the BH being so wide I could not get the 3.5" downpipe past....grrrh.

So sense this is a performance car I figured I need a quality turbo torque converter anyways.  I stopped last fall to pickup this spring.  Anyways I need 302/351 28oz flexplate, and proper bellhousing.  It looks like any of the 70's mustangs one should work.  I need the 157 tooth design.  So guys....are I missing anything.  P.S.  I already have the 157 tooth spacer.

Thanks,

Travis

I still have the c4 and bellhousing from my 68 mustang at my parents farm. The trans was from a 70, next time I am out there I can check to see what it is. Do you have any dimensions, I don't have anything to compare it to and not sure the flexplate is with it.

Made it out to the farm today, the bell housing on my c4 is for the 164 tooth.
