It will bolt right in and still be an SM 420 just with open drive. Same trans with different tail shaft and extension housing.

SM 420 ran from 47 to 67 and SM 465 started in 68 and ran through 91.

48 Chev 3100 that will run a 292 Six.
71 GMC 2500 that is getting a Cad 500 transplant.
77 C 30 dualie, 454, 4 speed with a 10 foot flatbed and hoist. It does the heavy work and hauls the projects around.
