fly wheel bolt patern

[crazygn]

i run a th350 1976 pontiac trans, i need a new stall but i dont know what bolt patern they are , some of the stalls say small , large and some say dual partern.

any one know what i will need to run. I run a tci 2000 stall now but dont know the bolt partern, will the dual work and is there any thing else i will need to no like the shaft or any thing when buying it.

thanks

Most 166-tooth Pontiac flexplates have dual patterns. What part # TCI converter do you have now? I'll tell you what the bolt pattern is.

One is a jw performance stall with a large bolt pattern and the other is a tci dual bolt pattern stall both for a th350 , thats really all i know.


thanks
