Question: Hi, I am looking for an NP205 to put behind a GM 4x4 NV4500 for my project truck. I think the simplest option would be a customization round pattern, 32 spline input with an Advance Adapters spacer. I think these were used with the TH400 transmission. Is this transfer case one that you can provide or build or possibly recommend alternatives? Thanks!Answer: We can build a customization round pattern NP205 but there will be tail modifications that you can make on the NV4500 to be made due to the space needed for the shift rail.  A 712529 bracket will also be needed to mount the shifter for the NP205 your cost $75.00. This transfer case is part number TCGM003 cost is $1000 outright plus freight.
