How comfortable are the original seats with new repop foam? I've never had the pleasure of sitting on a seat that wasn't blown out, and would like to correct this in the next few months. My choice will be to order new foams, have an upholstery shop cut custom foam, or look at replacement seats. Not sure I want to put high back later model seats in (just from the looks of others I have seen).

Second question, can you add the repop headrests to a '68 frame?
