GM 4L80 2WD NP205 71-84 fig 8 TC

Advance Adapter

The GM 4L80E 2WD transmission adapter to the GM NP205 is 4.00 in length. And the overall length of this transmission and adapter is 30.00″. Adapter material is 356 T-6 heat treated aluminum alloy. The adapter has a provision for a factory GM transmission mount. The adapter kit includes an adapter housing, new input with 32 spline, input gear bearing, gaskets, seal, fastening hardware and adapter instructions.

Transfer Case

The adapter assembly fits 1971-84 GM NP205 with a figure 8 front bolt pattern, and is designed to replace the 10 or 27 spline male inputs. If the GM NP205 is equipped with a 32 spline female input, the new 32 spline input that is included in the kit will not be needed. Call our tech line for more info.
