eddeere Posted November 28, 2018 Share Posted November 28, 2018 One step forward two back . Got the fenders mounted without a scratch . Put the new bumper on noticed the right fender was 1/2 "lower than left. Closer examination the core support was about 3/16 lower where the new rubber bushings were installed . Do not know what to do, shim the bushings ? Would like to pull the core support but do not know how to support the fenders when I do . 1 Quote Link to comment https://www.bigmacktrucks.com/topic/54911-core-support/ Share on other sites More sharing options...
41chevy Posted November 28, 2018 Share Posted November 28, 2018 (edited) No way to just loosen it and slide in 3/16 to 1/4 inches of body shims? They do come in long versions.

j hancock Posted November 28, 2018 Share Posted November 28, 2018 Shims are an old trucks best friend. Easy peasy. Used a couple on my B75 while hanging the sheet metal. 1 Quote JimIt doesn't cost anything to pay attention.

HarryS Posted November 28, 2018 Share Posted November 28, 2018 Yes, I had the same issues in several places on the front sheet metal. As Jim said shims and thick washers to the rescue.

Freightrain Posted November 28, 2018 Share Posted November 28, 2018 ORRRRR..........just slot the bumper holes in the frame and move it til it matches the front end?? LOL!! I agree, slip the bolt out, jack the support up and slip in a thick washer(or two). Quote Larry 1959 B61 Liv'n Large......................

eddeere Posted November 29, 2018 Author Share Posted November 29, 2018 Thanks everyone . I used some stainless shims 1/4" Pried the core support up and slid them in .Still can not figure why the support would not go down level . Looks ok now .

Hobert62 Posted December 1, 2018 Share Posted December 1, 2018 My B was off exactly the same as yours. Maybe the high torque over the years has stuff pulled. I added a washer or two and also enlarged bumper holes some.

JoeH Posted March 3, 2019 Share Posted March 3, 2019 My 79 R686st leans the same way, I assume it's saggy springs or to compensate for crown in the road. Quote Link to comment https://www.bigmacktrucks.com/topic/54911-core-support/#findComment-417082 Share on other sites More sharing options...
