Hello I needed some seals in a hurry (ie same day) and this website helped me cross my old victor oil seal from a '79 Jayco into something the local auto parts store had in stock. I paid more for them but I got the job done same day. It might help out someone in the future. http://www2.chicago-rawhide.com/popup_parts_lookup_457012.htm For the record the seals were these http://www.etrailer.com/p-RG06-020.htm but i couldn't wait for the shipping time. Cheers!!
