[99 to Life]

I think this link might help with some specs, unfortunately the most important one (lengths) are not on here. I do have another diagram I need to find, that gave all the measurements from the actual truck.

let me know if it works or not

I was so convinced that the s-10 route was the best. But the more I see OG
frames the more I like them. BUT, you can literally buy one of these trucks for the cost of an MII setup. If I were you, had the money I would try the MII set up first, since you already have a frame. Definitely need to box it in, in some areas for sure. All this IF your frame seems structurally strong enough.
