Chevy & GMC Vans

Hey everyone, quick question:

I came across a 94 astro that someone is parting out. Other than the obvious difference in front ends from 94-95, will all the awd gear be the same? Drive shafts n' stuff? Calipers as well? Also will the older style vans' windsheilds fit in the newer front ends?

Thanks

All the drive train parts will be the same. The only drive train difference is the tranny itself. The electronics are different.

its the same windsheild from 85-05
