I'm installing a 2" re on a 01 and i broke all 4 rear shock bolts off after a buddy has been telling me for 2 weeks bp them . after reading 3 pages on the subject i found that bp doesnt always get the job done ,so now i don't feel so bad. my question is what works best? cutting the floor pan, hitting it with a punch from underneath,or welding new studs on to the broken bolt i hate drilling and i would like 2 get my mom her xj tomorrow that's the only thing holding me up
