yeah I think the 60 front is 9.5, but the birfs are the same size as mini truck. So ultimately if you could build a custom front axle using the 60 centersection with 80 series axles and birfs and the custom high steer knuckles that billybob13 is coming out with, that would be a sick axle. But then you wouldnt have a high pinion front. I really want the high pinion. I guess you just cant have it all! ha ha
