I also have an 86 which I bought for......... $1 (just to satisfy the legal obligations of a title transfer).
The cab is half red and half black. The final color will be red. I snagged a new driver's door from the wrecker for $40. I'm currently prepping/painting it before installing the lock cylinder, handle and door card from my current truck.
Here are 2 BEFORE and AFTER pics...
I still need a nother coat of red but I'll do that later this year or in the Spring.
Cheers !!
