    My friend has an ailing NP203 in his Jimmy and would like to replace it with an NP205. However, NP205's for TH350's are hard to find around here, and the driveshafts to fit them in a Blazer are even harder to find.

    Is an NP208 another option? I know that the NP205 is the strongest, but an NP208 is plenty strong for this application. I like the lower gearset of the 208, and 208's are more plentiful than 205's. But most 208's seem to be behind TH700's, not TH350's.

    Were there NP208's offered for TH350's? What's the difference between a 208 that's bolted to a TH350, and one that's bolted to a Th700? Is the input gear different? Is the adapter different?

    Thanks!

    I know the factory used TH350's with NP208's, but I don't know the combination of adapter, input gear and output shaft required to make it work. Maybe post on the big board and see if anyone else knows?

  4. th350s that came with 208s have a longer output shaft
