So, I have decided to part ways with my 1980 frame. Needs too much work to be use-able and I do not have that sort of time.I will be using the axles and driveshafts off of it.
On a better note, I got in contact with a guy that has a 76' k30 chassis complete roller, sandblasted and powder coated for sale for $1000 I am going to snatch up. Has some extra bracing in it and will speed up the process of the truck tenfold.
Little update here. As I previously mentioned I have ditched my old 1980 frame for a better frame. I'm fairly excited about this and have a feeling the overall outcome will be much better with a more solid frame.
Rear end of the frame needs a bit of grinding and paint, but there looks to me a lot of extra bracing.
Noticed you bought some stuff from MBRP. Did you ever see their 12v JK build? Took a 4-door and stretched the "bed" 18". Slightly irrelevant, but it may give you some ideas for the motor.
