1965 MMP's Barracuda Hemi swap! The Ever Changing Build

Wow Sorry for being dormant, life has a funny way of getting in the way.
Hey house is done! Did a ton of business travailing ugh, Was hit pretty bad while in my Dodge truck :-( sadly it didn't make it....
Bought a 72 GMC C2500 402 w/ th400 as a replacement. Then lowered it B-)

In the mean time I haven't touched the poor old Barracuda. But I did order the tri4 link kit for the rear. Confirmed I have a 8.25 rear and not a 7.25.. It is a posi or trulock diff from a 72 or newer. Gearing I'm still not sure about.
Got a ton of hard to find parts for bmw on ebay. As soon as they sell. I'll be investing in a Qa1 front end and US Car Tool sub frame parts...
