hi all, am building the frame for my 1928 model a tudor the plans i have call for it to be 35" at the rear cross member, seems narrow to me, the stock frame is about 42" wide at rear, the rearend i am using has spring mounts that i could use if i made new frame 42", anyone know of any reason the 42" frame will not work, would like to channel body also, this is my first attempt and i am trying to get this right, thanks for any info
