Another thread I dont know where to post but this seems appropriate haha!
When I lifted my Tacoma I bought an All Pro Ubolt flip kit with my leafs. I didnt have the money to buy new bump stops and the factory bumps obviously dontfit on the flip kit the same way they do normally so I used some left over 1/4" X 1" 4ft steel flat i bought from Lowes and cut 4 lengths long enough to pass over boght legs on the factory bump stops. I cut two notches out of the sides of each length so that the U bolts could fit in them. The factory bumps have the lips on the edges of the legs on the side that curve upwards and the held the 4 peices inwhile the bolts on the flip kit held the lengths down. Crappy explanation I know but here a few pics that might help.
