17" wheel offset '67 barracuda

Autoxcuda, I'am using a '73 k-member with factory 11.75" disk a 1.125 swaybar Offset upper control arm bushings and .920 torsions. From what I have measured with the 20mm offset 8x17 rims the 40mm offset 7x17 rims should fit (I ordered one yesterday) with about an additional 5/16" more backspaceing, hopfully the 245/45/17 tires will clear the subframe and the fender. Do you know what size tire and rim width and back spaceing Tom reed is using on the freont of his '68 cuda? Also your web site was very helpfull and usefull for alot of the mods I have done to this car- Thanks
