after searchin the archives here a bunch , and a little on the hamb , i need some advice on chosing a gm 7.5 in rear end for my g/str , and i have a question for the roadster guys about body widths and rear axle track widths ect. i bought 32 frame rails from vhr , frame will be completed by them later this year and im wanting to put a 29 polyform on it but cant find rear bodywitdh dimensions and havent contacted polyform on it yet , but im thinking my rear axle should in the 56 in neighborhood as far as an outer drum to drum width ? hambers say a 3in wheel off set looks proper and will keep the tires close to the fenders ?,is this right ? is that good for bville ? how close does that leave me between the body and tire with goodyear 28s ? and for the rear end guys(thanks tony) , what years and models of gm 7.5 2 series would fit this kinda low buck , low tech, low hp build ? im hoping sparky will chime in on this , you seem to be the resident 7.5 guru. i'll start a build thread after i get the completed frame from vhr some time after sw this year. meanwhile , please feel free to fill in any blanks in my questions here . its a great feelin for me to finally be purchasing parts and getting this project going in , well , some direction . dont forget your double smileys. thanks for your help. mitchell
