Local salvage yards here in Va. Reasonably priced frames are everywhere, except the rustbelt states where everybody needs one and new Jeeps would be less expensive to buy. I've lived in VT and CT.
Getting the cash for an overpriced frame and hiding the cost from the wife. It's your money and Jeep though. Best of luck.
p.s. I'm just kidding. I hide everything concerning money from the wife.
I think @TheBoogieman is on the right track, donor Jeep. Cheap totaled Jeep with a good frame.
Isn’t the OP in Kalifornia? SGTJEEP might have what is needed. Frame, complete wreck, parts, etc.
