Simple question, can't find simple answer....

My 68SWB is being bagged at the moment. I just want to throw some stock truck rally wheels on it. But I want 15x10's in the rear. I see summit sells them with a 5" or 4.5" backspace. I've searched and searched, but can't find a straight answer. I want as much dish as I can get AND be able to tuck the tire up in the well. HELP PLEASE, need to order very soon! Pics, of both 4.5 and 5 with a good tire on them would help. Thanks in advance..

Oh, I got rid of the 22's. Here's the truck.

I run 15x12 with 6.5 bs and they had about 1/2" room so i opened it up a little. Be aware that a 71-72 rear is an inch wider. I run a 67 rearend

I'm just looking for the BS that will fit up inside the stock rear fender well. 4.5 or 5.

In my opinion on a 10" rim with your drop 4.5 is going to put u close to the outer lip depending on how much thie tire ballons out i would be happieir with the 5 but i dont know if it will clear the inner

So maybe a 5" and then I could use a spacer to fine tune it....

thats what i would do because it is gonna be tight and if you still have trailing arms it could shift side to side enough to rub. mine cleared but i know a bump or shift would make em rub thats why I opened em up some. here is some pics of mine before I opened them up. If you want to go the measurement route check your clearances and then pick a tire. most will advertize the section width. subtract wheel width from section width devide that by two then measure out to where your rim edge is and add the # you came up with and thats where your tire will be.
