Today I drove over to Honeoye Falls (just south of Rochester) to pick up a set of used, but complete and original rear quarters. The passenger side quarter has some ripples in it, a tiny bit of surface rust, and is a bit messed up at the front where it attaches to the B-pillar, but for what I need, it will work nicely. The ripples I can massage out before I weld it on.
These quarters came off of an 87 Blazer if I remember correctly so if I use the whole passenger quarter, I will have to change over to using a fuel door. I have to look into what is different between this and what is currently on my truck now.
I am itching to start cutting panels off, but my schedule right now sucks. I am way too busy with other things to make time for the K5. I am content right now to be able to drive it around!
