truck stance/ifs install
 

I am installing a mustang 11 ifs on my 53 gmc long bed also putting 68 tempest rear with 2 in lowering blocks. I want a even stance on truck not real low what tire sizes should I use ? Any suggestions or ideas. I am installing rear first with tires to get riding height then ifs. Truck has no front end or motor or bed on it now. Any help appreciated. Thanks
