Were the early frames stamped for ID/MODEL numbers.
If so where.

I don't mind the 3800 frame as long as I get the right spindle parts, king pins, wheel bearings inner and outer.

I have the old numbers on the bearings but trying to find source for roller bearing upgrades which is what started my line of what is in the box.
