Back to the power regulators. Thanks for posting that alert on the screws. I am going to put in power windows too, so would appreciate any feedback on that kit, as well as others you may have looked at.
Since you are doing the body work now, I would WELD IN the screws, so that you end up with "studs" on the inside of the door! grind the outside smooth and proceed on with your filler, primer, and blocking.
Only 104 degrees
here this week, load up the trailer and come to Texas!! LOL.
Looking good, don't rush the prep. 100% of a good finish is the prep.
