Is there enough length on the axles to do this? We did the same thing on one of my scamps that had the tiny rear end in it. The truck had the same spline but was a thicker shaft. We put a cheep spool in it we found at a swap meet and a rebuilt 360 in it, and pounded the pi$$ out of it for a while. Full time posi is fun with little 70R/14 tires roasting for a couple hundred ft. Snap your neck, mega G-force launch, is all I want!

I think it's $110 for the housing & $110 for the axles & $55 for the perches(plus new perches) plus the shipping to Portland Indiana & back. Be sure & tell them to relocate the perches on the other side of the(truck) housing(I forgot to do that & they didn't catch it either ) & they will relocate them at 43.125" & factory was 43.02". that amt I wouldn't think it'd be a problem but I wanted mine factory perfect so I gave them that dimention rather than telling them "to A body dimentions" . live every 24 hour block of time like it's your last day on earth

If the aftermarket axles are configured with the B, C, E body flange dimension (most are) the A body brake drums, shoes and backing plates won't work. The INTERNET, the MISinformation superhighway

If your having the truck BBP 8&3/4 narrowed for your A body the drums/backing plates/shoes etc will still fit OK, they are just shortening the axles/housing inward to fit your A body. I would check the wheels/tires you intend to use as that MAY slightly change how much you want them to narrow it. Measure twice cut once is good advice. live every 24 hour block of time like it's your last day on earth

A 52" wide housing will yield an identical assembly width when used with standard 5 x 4 1/2" axle flange stand out. Unfortunately, the stock housing ends get a little close to the perches, so I usually make (5 x 4 1/2" pattern) A-body housings 52 1/4" wide. Contact info
