ok I just bought a gm D44 front axle for my 94. my trans is a 4l65, but I may end up swapping in a nv4500 sometime soon. what t case do I need to look for that will bolt up without any adapters and be a pass drop?

32 spline np241 from a 88-91 3/4 ton suburban, you will need to make some linkage to run pass drop, if you stay with the 4l60e you need a 27 spline from a 1/2 ton burban or k5

NP241 Passenger drop in 88-89 are mechanical speedometer. They switched to electric speedometer in 90-91. You will want one from these years unless you want to adapt or run a mechanical speedometer. 1/2ton with 700R4 will be 27 spline and will mate to your 4L60e, 3/4ton with a TH400, 4L80e, or SM465 will have a 32 spline input to match up to a NV4500.

NP205 with electric speedometer was only available on 91 V-series 3500 Crewcab trucks. Stupidly difficult to find.

91 not 92, the crew in 92 was a gmt400 and yes the electric vss was a 1 year thing in the 205, the 205 housing can be modified to use a 88-90 th400 tone ring and the vss sensor from a np241
