Steel wheel advice needed

[waspp]

Ok I am looking to use steel wheels on my 63. Originally I wanted to use the white dog dishes that came with the truck but with a wider wheel. I am planning on using a dropped spindle with 6 lug discs. I have seen on some other posts that the 15x8 rallies rub in the front if the truck is lowered but a lot of people seem to use them, is that the case? Also what back spacing do I need if I choose to order or buy a steel wheel? It seems a wider wheel would work on the rear maybe up to 10" and maybe a 7" would be good on the front. What have you guys found out and what do you recommend? Thanks in advance
