After seeing the going rates to build up a 8 3/4 sure grip from axle to axle I was wondering if there were other rears out there suitable for a 450 HP Ebody cruiser? I only had a 7 1/4 under the convertible so I need something beefier for the 5.7 hemi. it looks smarter to build a Dana or Strange S60 from scratch than trying to build a 8 3/4 with all new parts. I didn't mind using a Ford 9 inch under my other race cars, but not in my Mopar! Years ago I remember the Mopar mags putting Dodge truck/Dakota type rears under their project cars. I guess I could build a dana for the future racecar barracuda and use it's 8.75 under the convert, but would still have to source a suregrip. Just looking for ideas out there.
