Yes. The I6 is a longer engine. The transfer case is in the same location. The difference is in the length of the adaptor. The short one is from an I6 application. About 15 years ago they were slightly desirable as there was a cheap adaptor/spacer to make an NP435 bolt to the D20. You bolt the spacer to the short I6 tailhousing and you get a V8 length tailhousing that works with a NP435.
