Used SM465 mainshaft and 3rd gear....Replaced these as part of adapting the SM465 to D18. 3rd gear is lower left of pic. Also have 2 (of the three) new mainshaft bushings still in box.
This is the early 4wd 10spline version...according to Novak:
The earlier era of the SM465 include the 1968 - 1978 transmissions. There were both 2wd and 4wd versions. Internally, they are identical to each with the exception of the transmission mainshaft. The 4wd version of this mainshaft (or "output shaft") has a 10-spline output with a 2-5/8" stickout and an accompanying 4wd adapter housing.
$60 - I can ship flat rate box for $20 if needed.
