Transfer case skid plates look easy enough to make, but I currently do not have the equipment to make one. I will in the future. GM has discontinued skid plates for the Generation 2 truck.
One day, I would like to start making and selling stuff for the GM Gen. 1 and 2 trucks, which are not available from the factory or any aftermarket companies, such as a 4L80E to NP205 transfer case adapter, skid plates, and the stabilizer bars that run from the bell housing to the engine mounts, and the transfer case to the bell housing; along with any other items that I can come up with, which are not available from any other source.
