flip kit Help -90 chevy dually

Just wondering if the factory axle u-bolts are long enough to use with a axle flip kit, got the kit of ebay, so it didnt come with everything. Just want to make sure i have everything before i start on it.

thanks

Just wonder also, i have access to a torch or plasma cutter, does a sawsal work well for cutting the frame for c-notch, or would a cut-off wheel work better.

thanks again

yes a cut off wheel works fine... and no the stock ubolts wont wotk because there completely different with the flip.

Just use the cut off wheel and drill a 3/8 or 1/2" hole at all of the changes in direction to get a nice rounded corner.
