76 k20 driveshaft to front of transfer case front end yoke question, looks and measures similar to Dorman 697-500

[gbnbrb123]

I am having some confusion, my son has a 76 k20 automatic with what I believe to be a np203 transfer case, 346321. The front axle is a dana 44. The problem is everything says the yoke should be 26 splines, mine is 30, plus not everything measures correct. The hub diameter is 1.75in, c/l to end 3.4in, u joint width near 3.3in, total length near 3.4in. The yoke was obviously damaged from the prior owner, just trying to figure out what I need to purchase for the front of the transfer case to attach to the driveshaft. Measurements seem close near spot on with the Dorman 697-500, except for the total length. Thanks, Nick

Well I found the part # SPI-2-4-4801, apparently 30 spline female that is no longer made for the NP203.

Should be lots in the scrap yards. Someone here might have an extra.
