Why not beef up a big  10 bolt  ? confuse  It already fits and costs less    will handle 400 hp

I mini tubed the car Carl so I need the diff shortened,
DSE recommends 52.250 flange to flange, so I can put
17x11 rims with a 315 tire.

Since your moving your springs inboard and don't have your leaf spring center to center measurement just get the rearend without the saddles welded in place. Can still put in car with unwelded perches and tighten u bolts to move around until you get your ride height. Think most motor trans were down 3-5 deg. Sorry, no good at math. But I can count to 6,12 and 24.biggrin

I can't see what model and year your car is but I will tell you the standard rear in an Acadian/Nova is 52.5" flange to flange.  The 10 bolts used in 64-67 were small ring gear but 28 spline and could handle 400hp when built with good parts.  There are a limited number of 12 bolts around that were in the SS and SD cars also.  I have been looking for a wider rear in order to use it in my gasser so I'm not interested in a rear that narrow but in looking I have come across several narrowed (primarily 9") rears available for less than $1500 on eBay.

My good friend here in Michigan builds race car frames, cages and custom builds complete 12 bolts to your specs with all new parts for $2500 US.

Its a 67 Canso forespeed,and you are correct on the length.I was over a buddies of mine the other day shooting the s....,
about what im doing with the car.He has his own shop,and mentioned hes got a 12 bolt.I forgot all about him building my
sons rear end and a few other ppls I know that race at Cayuga.So needless to say hes building that 1 for me.Bonus is if it
screws up I don't have to go to the states to shoot him,just 10 miles down the road.lol
