There are a number of transfer-case parts I am seeking as I am undergoing a NP203 to NP205 t-case conversion: 1. 27-spline input shaft for NP205 2. If input shaft is not an option, then a 27-spline-to-10-Spline-Coupler if such an animal exists outside of Advance Adapters. Failing this, if you know where some of this stuff is for sale it would be greatly appreciated if you would pass this info along. Thanks.
