Jamb and Dash Cutouts for Power Doors

[GonicGM]

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?

Can no one supply 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.

Found all the info from junkyard Blazer.
On the front of the door halfway between the hinges, there are three dimples. The center is for the 1.5" main feed hole, cut with 1.5" hole saw. The two outboard of that are for the 3/16" rivets.
Just under the dashboard are likewise dimples, they are about and inch below the dash and about 3.5-4" in from the weatherstrip lip. These again are for the 1.5" wire feed grommet. The upper cutout/notch in the vinyl kickpanel will align with this hole.
Lastly are the door jamb/cowl modifications with the center hole being an oval, 1.25" wide, 2" tall. Halfway between the door hinges are four dimples in alignment. The two outer are for the 3/16 rivets. The two inner provide you the centers for a 1.25" hole saw. Once done with the holesaw, you will have a relative "8". Simply cut the verical line tangent to the major hole diameter and dress leaving a nice oval.

I added electric locks and windows to my 79 C20. I used the rubber tubes from the rear doors of a late 80's or so chevy station wagon. I made holes to fit the boots, but I had to drill with a hole saw then use a die grinder to open them up. It was a PITA, but that was also 13 years ago and I had just started to get into working with metal.

If only I had seen your post 13 years ago
