    Will someone make me all the engine mounts for an ls1 swap into a 1988 gmc sierra? Right now it has a v6 5 speed granny, and I am gunna put in an LS1 with LS6 IM and a t-56 6 speed -- If someone can make me ALL motor mounts (Don't need AC because I don't have AC) :frown: that would be awesome. Someone gimme a price on them and i'll buy em from you! Also if anyone has ANY other resources for something like this -- (LS1 into a full size chevy) then hook me up with some links! THANKS!

    The plates look like this and will bolt up to your existing hardware and mounts. You will need to drill one hole in your hardware plate that bolts to this plate
