I mini tubed a 70 Dart and moved the leafs under the frame rail. I could fit an N50 15 for street duty and 28x12 slicks for the track. I had to modify the bottom of the front wheel well opening so the N50 15 would not rub. If I had the perfect wheel offset I could have had a little more outside clearance and may have been able to avoid that slight modification.
pick your wheels first and work the housing width afterwards to get the right clearances.
