[Mixup]

I have a 99 Silverado bench in my 69. The front holes line up perfect but you have to drill holes for the rear and space it up level with the front. It sat to high on the ledge that the front of the seat sits on so I cut a notch and rewelded it so the back sits on the floor instead of using spacers. It seems to be ok but I'm installing new carpet and insulation and haven't driven it with the new seat yet.
