c & k 30 1ton frames or even c20 crew cab frames are about 2" taller and the whole middle section from the firewall area to past the rear axle is totally different spacing for brackets like this . the frame hangs down the extra 2" on the bottom side . this is why the 2wd and 4wd trans - tcase cross members are specific to these frames .

i am not saying you cant make a filler piece to make up the space gap . but it by no means is a bolt in thing to do .

if you can fab i am sure you could make your own mount setup for the stuff you want to do .
