International Auto Parts sells the bottom seat foam with the wires already attached however many will just weld up a new frame from C-Channel obtained at the local scrap yard and purchase some upholstery wire to fabricate their own especially if the foam is still in good shape.

The gent I purchased mine from threw out the rusted out seats/frames and put in some Second-Hand Garage Pro Recaro Knock-Offs however I would have preferred having the original seats to use as patterns to re-fabricate new frames from.
