I am adding power door accessories to my 85 K30. I noted that the donor Suburban had OEM jamb cutouts for the rubber accordians that were oval, taller than wide. Does anyone have the dimensions, height and width of oval? Images or dimensions or anything? No one has a stripped cab or tub that they can hold up a ruler or tape measure at these holes? I have doors to reference for those holes. Need info on door jambs and just below dash inside, I think. I believe the jamb holes are oval, need size and location and below there are round holes just under dash, nred location and diameter. Would appreciate images, locations, dimensions. I have nothing to work with. Thanks in advance.
