Will a b-body length dana fit under a 70 cuda with the springs in stock location? The perches aren't my concern but the tires hitting the springs is.

Or if anyone knows the stock width of a b-body dana compared to a 70 cuda's flange to flange?

the stock springs will work but you need offset shackles and hangers.

i put a b body 8 34 and a b body ish dana 60 recently in ym challenger

What year B-body? The 71 B-body Dana's are supposed to be the same width as 70-74 E-bodies.

Doctordiff has all the components you need to do the conversion

I will weld the perches on where ever I need them to match my springs. What will dr diffs kit do for me? Let me clarify that the perches are not on the b-body rear end right now.

does anyone know the flange to flange measurements on dana 60's for each body style?

here you go
