i have a 48 gmc 1/2 ton... i want to lower it a few inches... i also want to put a v8 in it...and maybe put some 5 lugs rims on instead of six...would it be better to get a s10 frame to put under..or add parts to the old frame...this is my first big project...i am learning things on my own...any info would be a big help...thanks
