[inkfamous13]

At the pick n pull near me there are closing and there is a complete nice looks recently reworked crossmember on a 1990 chevy van 20. It looks just like any 73-85 truck or up to 91 burb crossmember swap for my 1966 c20? But i need to know asap if its worth it to pull out. Will it fit my frame? Ive got tomorrow before its gone or monday latest but ive got joint problems and deal with lots of pain from heavy work and dont mind at all if it will fit. Please help need info. Its a 5 lug disk brake front end. Ive loosened the side frame bolts but they have it sitting on welded rims on the crossmember and being a van id have to loosen wiring motor have them lift van then motor will still be on crossmember fliped over in dirt? Lol if its a fit ill go grab it its half price and being there crushing cars i might beable to have them cut frame for me? Any info is appreciated.
