Older Cushman cart, info needed

[Gunner7800]

I recently acquired an older Cushman cart. My best guess from what I found online is that it's a late 1960's Golfster Deluxe. I've been all over it and haven't been able to find a serial tag. Does anyone have experience with these? I posted another thread about a 1960's EZGO and I found another parts cart for it. But I fell in love with this cart and am thinking I'll work with this one first. It's a 36V with a GE motor. I think it's pretty much complete. I thought I'd upgrade it to a solid state system rather than go back to the resistors. Not sure if I want to dump that much money into it but, this is a cart I plan to keep.
