Ok then let’s switch the question to this.
Is there a good substitute for a 58”-60” 12 bolt that can be had at a salvage yard? Fully updating the internals is no problem. For what I’m doing and with the good service 12 bolts have given me I just can’t see spending 2000-3000 on a 9” or a strange.
It’s getting nearly impossible to find 12 bolt car donor housings but truck housings are still around. I have narrowed and set up several drag race 12 bolts way back in the day but I no longer have the 2.5” ground drill rod and donuts but I’m sure I can locate one if I need to narrow a housing and if aftermarket axles are available. 500 hp and 500 fp is the target area that I will be in. These will be in hot rod vintage retros.
Like this this and this lol.
What were these 8.5.s in I’ll go to one of the yards and have a look see.
