Interesting trivia about those radius arm shock mounts. Over the years we have seen some tires make contact with them and others don't. Because of so many tire and wheel options out there it's hard to know who will have to adjust the bumps and who won't. Early this year one of our Bronco's had a tire rubbing on the shock mount, We wheeled it like that once real hard with no issue then adjusted the steering stop after we got back.
Typically when running dual duff shocks, if you have a tire clearance issue you will find the back shock head will usually make contact with the tire before the mount. On custom applications like yours you have the option to play with it more and dial it in.
Cool build, fun to follow. Not sure if we have met, if you're a friend of Taskers we might have already. ;D
