dodge rears in a chevy????

[RootBreaker]

I have a chance to get 1978 dana 60 front and matching rear dana 80 for $400. My question is will they just bolt right in to a 1978 chevy 3/4 ton other than the steering components being different??? crossover at that point? Will the driveshafts match and will the spring pearches match????
also how much bigger is the dana80 than a 14bolt corp? and anyone have any specs on the dana80?
thanks

also what can a dana 80 take as a gear ratio that I can also put in a dana 60 to match?

Not sur eon your other question, but they compare the 14FF to the Dana 70 so the 80 will be stronger.

I use a rear 30 spline Dodge Dana 60 on my half ton and a 35 spline Gm Dana 60 up front. I only had to relocate the spring perches on the rear diff, and use wheels will smaller offset to compensate for the narrower width of the Dodge Dana 60 compared with the front GM Dana 60, works great with 35's , and I don't think I'll have any problems with 37's.
The Dana 80 is a very strong axle, but I think it will stick way out your rear fenders
