another note... when im buying parts for my truck, as long as im not buying tbi specific stuff, I typically search for 1986 c10 parts instead of 87 r10 parts... most people have NO idea what an r10 is but everyone knows what a c10 is.
I just replaced my tail lights with new ones from lmc. I have no complaints with them. they look 100% better than the old original faded ones and fit nice too.
By far my favorite truck there. Just a very clean uncut close to original example of a 87 R10. I loved it....but wanted to cut it up and slam it at the same time
