i am running 22x9.5" panthers on it right now but am rubbing on the passenger side. i think it would be less of a headache to just go with the 20's and smaller width so they can fit better in the fender. i am also running a 5.5 inch static drop in the front. am i going to have to put spacers on the front or back for fitment?

Here are a couple of shots of the earlier 338's. 8.5 x 20 in front with a 245/40 and a 1" spacer. The rear is a 20 x 10 with 275/45's and a 1.5" spacer.

I had room in the back with that set up *before* I put on the 1" spacers...But only by 1/4" before it hit the bed on the inside edge. The ECE adjustable
panhard bar allowed me to center things to get the 1/4" even on both sides.

But the 338 folks only offered that 6.225" BS (I'm talking rear...I don't remember the front stats)
when I bought them. And, I was too far under the bed. So, at first I went with the 1" spacers in the rear.

Next was a move of the spacers to the front. And new spacers... a little wider (1.5")..... on the rear.

So, this is how she sits now with the ECE 4.5/6 drop (spindles and springs in the front, and springs in the rear....
...Not that it matters for this conversation, but a big, fat anti-sway bar up front and also ECE shock relocation
kit all around.

Oops! I forgot...The rear end is '71. That, I believe, is important. Width-wise....Just to make these stats make sense.

Anybody have any pointers for running 20x10 Boss 338's on a 60-66 fleetside with a '72 rear axle? My rear axle overall length is 65". Should I order the 5.5" bs or the 6.23" bs. I want to run a 295/40/20 tire. Thanks!!

First off let me qualify this by saying .... I havent suffered thru 3-4 years of frustration with this wheel and secondly I am in no way trying to argue with anyone .... Just stating my opinions is all. I can tell you... all I have read is this wheel wont fit these trucks , Yet the first 3 trucks I went to put them on ... they fit with absolutelly no mods whatsoever ..... and that is on 1-1/4 thick rotors that I personally measured. Yes you guys are right .... they dont fit everything as evidenced by my 2wd blazer.... but so far I am batting 75% and I havent modified anything whatsoever.

It is personally one of my favorite all time wheels and also .... I love the fact that it is an AMERICAN made wheel. Again Im not tryin to argue , just trying to offer useful information and I dont claim to know it all ....... I tell lots of people to talk to lo-life everyday as he has a vast amount of knowledge concerning these trucks. Hope no one is offended ............ !

So lets say you grind down the rotor hub dimensions a little bit, so the boss wheel is not touching on the wheel inside. Would that work just the studs holding the wheel not the hub?;)
