64 GMC swb transmission

[Jduckett]

Hey guys

I'm wanting to swap my 3speed transmission 64 GMC swb to a 3 speed synchro transmission. Can anyone give advice and part# and model of a suitable transmission. Would a SM326 work and be a direct bolt in. Thank in advance for any advice.

I believe the Synchro 326 is a bolt in for a non Synchro 318. May need slip yoke change (spline count), and possible: linkage, speedo cable, and speedo gear modification. BW OD available for those. Hens teeth.
