Does anyone know what the function or difference is between the heater core seal # 3929024 and 9789711. The 711 shows for 67 and the other for 68 but some parts books show the 711 for 67 and 68. The AIMs each show 68 and 67 respectively.
I'm just wondering because all the heater box seal kits have a generic flimsy foam for that seal and some parts places say if you want the correct seal you have to order ... which is a functional repro of the original 3929024. However, I found a place that still has the original gm part 9789711. If it's functionally and appearing the same as the 3929024, I thought I would get it as it's the same price (well actually cheaper) than the repro.
