No problem, send us the outer and inner diameter, the overall length and the depth of the hole and we can try and custom machine a bushing for your truck. Or if you have a soft pivot cup that fits, mail it to us and we can use that for a template. And no spare cup? No problem, mail us the whole truck and we can make a cup to fit. But mpost important is to MEASURE the diameter of the hole in your truck base plate and the diameter of the pivot end on your hanger and use that to select the proper size pivot cup for your application. We try to keep the fitment information up to date, but the proper size cup for your truck is the one that matches the sizes measured and not what is listed on the web page. And if you have any fitment information not on the page, send it to us to add to the page so we can keep it up to date.   (13/70)
