I was looking at an 88 K5 blazer today that looks like someone transplanted a TH400 into it. It has a NP208 transfer on the TH400, my question is what would the spline count be on the TH400? Would this TH400 work in a doubler set-up with no mods? Is the output shaft longer/shorter 32 spline? <font color=purple>I Like my Burb'n on the ROCKS !! <font color=black>Imported to Kentucky through military channels !!
