I have 84 k5. just changed lifts I went from a springshop made 2.5 that was suposed to be a 4in. to a 6in. superlift. the problem is front driveshaft is hitting the crossmember. I know a few ways to fix it but would like some opinions on wich is the best. I can lower the crossmember with spacers between the frame and tcase. I can lower the crossmember and the tcase or I can notch the crossmember and weld a flat pice of plate across the bottom for strength.any help would be appreciated. oh yah one more my crossmember already has spacers between it and the frame is this stock there where on it when I got it there about 3/4 to 1in. long. thanks again.
