I have a kick only Panhead tranmission that I am re-installing in a '58 frame. Does anyone know the size of the bolt that goes into the bottom of the trans case through the mount tab in the frame? I must have lost it during disassembly.

#4323 3/8-16 N.C. x 1" hex bolt is what's listed.
Be sure and shim the gap, if it's not a flush fit between trans. boss to the frame ("5th") mount. If the trans boss fits flush, make sure the trans is sitting completely down in the base plate. check all the way around with .004" feeler gauge. A gap anywhere in the mounting will eventually crack the frame, or maybe the case, if it's the 5th mount that's gapped over 0.004".
