i recently did a full conver't conv. on my 1990, in additin to a full cage w/the feet tied togather i want to make the frame stronger. i was going to box in the frame under the cab but that would cause stress points at each end and it would be a biatch to do. so i decided to to add another cross member behind the x-fer case and box the frame where that attaches (maybe a cross member off a 2wd? just have to see what fits) and i was going to box the frame at the x-fer case cross member mount. p.s. if you have dropped your case and just have the 1in barrels between your frame and you cross member get rid of them asafp! those barrels give no support and the motor,tranny and x-fer case all depend on that mount to be soild, put a solid block of steel between in stead. any way has anybody added an extra csorr member?
