1971 Duster 340 4 speed numbers matching

Right, I was checking to see if the axles had been redrilled or replaced entirely. They are LBP correct? That's what the ad says.
4.30 is steep, but maybe those can go in the other 8-3/4" I just bought from you lol.

What can you tell me about the engine? Factory rebuild or is it pretty wild? Any specs you might have would be great. Simple bolt ons like intakes and air cleaners are fine.
Thanks

Yes large bolt. Gears are no big deal. I have a set of 3.55 I can include in the deal. For you
