So here is the 411.
Bullit calipers need 10x1.0x26.5mm banjo bolts. The non OEM ones that they sell that work in GT applications are 10x1.0x31mm and hit the piston on the Bullitt calipers.
I have confirmed the OEM size with Maxx and two other Ford parts places managers.
I call Buy Ford Racing today... well first I emailed them as their number is not listed. Was a polite email saying I bought my calipers from them and I would like to buy the correct bolts as they are near impossiable to get. And I also said "I really wish there was a heads up on this problem in your listings.
" and that was it. Wasnt being rude, just was making a suggestion. Well in the mean time I got their number under a different name so I spoke to the dude there and right off the bat he was just... IDK, harsh?
He answered the phone "DIVERSIFIED PRODUCTS MARKETING." and I said I am sorry, I may have dialed the wrong number.Is this Buy Ford Racing? And he snaps back "Thats what our site is called!" OK, I explain the issue and he says they dont sell the bolts and that LMR sells them. I explain that they are 31mm long and I need stock 26.5mm ones. Again he snaps back "I have it in my hand and I measured it! Its 31mm" Which of course raised the question "I thought you didnt have them?"

So he tells me they come with the brake lines and they are 31mm. I explain that my friend Maxx who runs the parts department at a large Ford dealer says they are 26.5mm and I believe him. To which Mr. Niceguy says "Hes wrong! He doesnt know what hes talking about!"
Fine, I had enough. That gave me the idea to go try and find some brake lines and see if they do come with them.... they dont. So I stopped at the Ford dealer by my work and ordered a set that will be here tomorrow. I didnt re-order from Maxx because if they happen to not work then its much easier to just walk in and get my cash back cause the little bastards were $50
So dont get Bullitt calipers. Spend the extra $40 and get the Cobra versions and you can re-use your old Banjo bolts.
