Slip on or press on drums ?

[sweetk30]

What year is stamped in ring gear is a big help .

But from what i can see on my phone zoomed in there early press on drum .

Were the wheel sits there is just 1 surface for the wheel center to register on and center up .

If they were slip on drum or even newer disc there would be two lip step . 1 for drum or disc and 1 for wheel .

And you look on the back side note the machined lip for the drum to center up .

Anymore better option is use a 99-newer 14ff from gas engine trucks . Same basic axle but disc brake AND parking brake . Just need 14x1.5mm lug nuts . And new leaf spring perches and shock mounts .
