Ah, '66 parts! So all I found (and bought) were those expensive ones. Once I got them I understood. '66 was an odd ball as MOPAR made several weird choices to change for one year only so the rear glass seal in not made (we have inquired it could be for a $50k tooling cost) and the roof rail seals are not "made". They are expensive on eBay because you find that someone spent a lot of time finding 3 profiles of seal material that will work and then they cut and bond these three piece together to make that seal so there is some labor involved there. Also Laysons will sell you 2 profiles that can be used to make the back glass seal. Everything else you can get from Detroit Muscle Technologies (if not out of stock)
