VA looking for some wheels for my 72 & a little help.

[billsbowtie]

i am looking for a set of 4 wheels for my 72 5 lug . i want something like a 15" by 8 torque trust wheel but may be interested in something else. so if you have something that will fit post pic.s and price.
now for the help. my truck has been lowered by c-notch in back and 2 1/2 in drop spinels in ft. my problem is in the rear i have 15 by 8 ralleys on it now and 265-70-15's tires and every now and then they will barely rub. i think the 15 by 8's have 3 1/2" back spaceing. ft. are 15 by 7 wheels tires are 225-70-15 they fit fine and are almost new . so i could get by with my ft. tires.
i need to no how much back spaceing i need or can get by with on rear and maybe a good size tire to use. thanks for any help bill
