zoom flywheel questions

I am building a mild 318. K&B flattops, performer rpm.intake , 56cc magnum closed chamber styled pro comp heads, nice comp cams cam kit. Eddy 650, prob about 375hp

Funny thing is i called up Zoom techline today. This guy couldent tell me weather or not this flywheel fit apps older than 1985, and then told me they dont make parts for those older cars!!! I was like WTF!!!

So i can assume that a standard 10.5" 32T splined mopar clutch would fit this flywheel then. Dowel pins and bolt holes line up then?
