Weight bias and c of g height

[stonebreaker]

Anyone know off the top of their heads what the front/rear weight bias is for a 91 S-10/Sonoma regular cab short bed?

Same for the height of the center of gravity?

I'm narrowing a caprice 8.5" rear end to fit under the truck, and since I'm going to have to fab up the suspension anyway, I figured a nice 3-link would be just the ticket for an autocross setup. I want to set the truck up with 100% antisquat, and to do that I need to know what the cg height is.

I know I can figure it out with scales and a jack, but I don't have a set of wheel scales and the truck currently does not run.

Thanks in advance,
