I don't know what the stock back spacing was on 15 x 7 Rallyes as my car came with aftermarket wheels. There is a section on this forum for suspension wheels and tires that you could check out. There are many discussions on this all over the forum; use the search tool. If you call any wheel vender or go on line to Summit,Coker, Jegs, etc.. they will list or tell you what stock back spacing was or should be. Remember you can always use spacers behind most wheels to space them out if you have room in the fenderwell.
As for your carpet question, try old JC Whitney. I think you can get carpet for damn near any car in any color of the rainbow for a lot less than most anywhere else. You can even order custom mats with names embroidered right in them.
