im getting an ifs v6 rear, im sure the guy will let me take spring plates, and ubolts. Im gunna take all he will let me get. 81 came with 3.90, I have already swapped front axles previously, so my front is 4.10, and rear is 3.90. I was always told this was so close of a ratio that it didnt matter. Im hopin for a lil more pep with 4.10 in rear tho, u guys think it will be noticeable? Thanks.
