8.75 it is, now i need to narrow it HELP

hi all

i posted a thread on here about the mopar 8.75 axle VS the ford explorer disc brake rear. well its settled i got an 8.75 from a 67 newport with a 742 center chunk 3.23 gears complete drum to drum for $100. price was always a consideration but trying to keep it mostly mopar was also. so when this one popped up with a 742 chunk i bought it.

so theres the big question, does anybody know where i can send the housing out to get it narrowed to a stock A body width, along with perches welded in. i can do the perches myself if need be, but the narrowing needs to be done with a jig to keep it all square.

plus what is the stock width for an 8.75 A body axle housing from backing plate flange to backing plate flange. i dont plan on narrowing the rear any less than stock width for an A body. i already have the perch width from the old axle at 43.25"

also what is the stock pinion angle for this setup in an A body if i have to put the perches in myself.

i plan on using new A body BBP axles with green bearings from mancini racing unless i can get my C body ones cut and resplined. anybody know where i can get the resplining done

can my drums, and backing plates from the 74 V8 dart parts car 7.25" axle be used on the 8.75" axle housing?? the mating flange looks like the same pattern, and the C body brakes look really too huge for the back end of the car.

if you want you can post here but also please email me privately at [email protected] as i am not on here often enough to get the posts.

thanks
matt
