houston54 i boxed the front with plans on boxing the rear. but i cut my last peice of plate steel up for the rear peices but i f@#$%& up and they didnot fit. i was thinking with just boxing the arches and making a shock cross member and a k member to the midle cross member would be fine but your commit about metal fatigue got me thinkn.but achipmunk said that he has had no problems omn his 37. also has me thinking wich is what i wanted you guys to do so i make the right choice. thank you all
