Haven't decided on the seat yet. The owner of the body shop where my truck is at has a '70 C10 that he has a custom leather seat in. It is a split bench with a fold down console. All tan leather and runs about $1400. He may sell it to me and buy a different one. If not I saw someone on here who took a seat ouf of a 05 tahoe and put in their truck and it looked awesome. The options are endless...
As far as the boards go. I cut the factory grove in them yes. I went on GMC Pauls to find the dimensions in order to cut them. I rough cut them on the saw mill then planed them down to what I needed. Cut them on the table saw and used a dado blade to get the groves correct. The close up of the one board is pretty cool. There were wood borers in the log and there are some cool holes and stuff in the boards.
The axle is original but has the updated disc brake kit. It came with it when I got the truck.
Here are some more pics. Thanks for looking everyone!
