Seeking some advice for what seems to be a confusing topic. Recently picked up a set of 17x8J Bullitts for my 67 Coupe. 1" spacer on rear with new studs and 1.25" in the front, but still getting a nasty rubbing on my UCA. Grinded and trimmed and while there's no more rubbing or grinding in reverse or drive..turning the wheels causes a significant grind...so i'm considering getting a tubular UCA from TCP or Global West..what are your thoughts?
I'm sure someone who has run bullitts will chime in....but I think there are particular year bullitts that fit better than others. Not 100% sure though. Do you know what year yours came off of?
Everything I've heard about the bullitt wheels is they are around 5.72 of backspacing and with a 1" spacer that puts them right in the sweet spot for 67-68 of 4.75 (4.72) of backspacing. With your spacer you're around 4.5" of backspacing which should still be fine. On my 67 coupe i have a set of MB wheels that 17x8 with 4.5" backspacing and I have plenty of clearance at the upper control arm.
Is your steering, brakes, suspension all stock? New or older and a bit worn? How is the alignment? That seems to have an effect on rubbing on larger wheels and tires. Does it grind throughout the whole range of turning? Or only at close to lock? And does it only happen when you are driving or does it grind when the car is stationary and turning the wheels also?
Sorry, I don't have a direct answer for you but I figure if we question enough stuff we can home in on the answer. - Brian

Got the adapters originally because 16" were doing the same. Did some searching on here and other sites and was recommended to go with 17''s. Hadn't tried without them. Thinking the tubular UCA's would give me the clearance...
$600 for the UCA
or 1000.00 for rims and tires that will fit from Mustangs Unlimited...bullitts as well...
I just looked and the 03 bullitts have 5.72 backspacing...so with your 1.25" spacer your wheels should have around 4.5" backspacing...which should work just fine. With 4.5" backspacing I would think if anything you would be closer to rubbing on the fender lip rather that the UCA. Does it rub/grind on both sides?
I'll try when I get home. It doesn't hit the fender at all..definitely all UCA. It was previously aligned so I can't say if there's any problems with aligning it..after grinding down the UCA i don't get very very slight rubbing in forward/reverse in a straight line..it's when I turn the wheels...from half to full lock out...i only drove it down the drive way...
Working at a startup I have to tackle things when i can with as much info as I can..which is why i tried grinding it like Open tracker did and so now I'm looking at tubular UCA....
BTW...I work at GoPro.com greatest company to work for!!
GoPro the camera company? Nice! With how many people run the bullitts with stock style UCA, I would hate for you to drop a bunch of $$$ if you dont have to.
I'm kind of with "wheelsup" measuring the actual backspacing without the spacer and have the alignment checked. Could be as simple as the wheels were not described accurately from who you bought them from or the alignment is off and causing an odd wheel angle.
Just had the alignment done not that long ago...i'll try it without the spacers...definitely not trying to spend money where I don't need too, but on the other hand it could be that the ball joint need replaced and it's causing the UCA to droop...it just hitting the upper bead and edge of the bottom lip...so frustrating..
WheelsUp..yes sir..that's the one...hahaha....we're hiring like crazy..
IMO if the suspension/steering is that wore out, then you would defiantly see horrible drivability issues.
I would check the UCA bushing (where it bolts to the shock tower) and the LCA bushings (at the frame mount) and of course the upper and lower ball joints. Something has to be pretty wore out if the rim is rubbing the UCA only when turning left or right.
The 'bushing' you are referring to is more than likely the dust boot for the ball joint. It plays no part in the functionality of the ball joint other than to simply retain grease and keep dirt out.
