Ryan, sorry I have retired. Actually my machinist friend who was in his late 60's when I made the nearly 100 sets 5 years ago has retired. I was happy to offer them at cost to keep him busy and to supplement his income. Now that he is no longer working in his shop, I don't have any incentive to do them.
As for clearance, absolutely. If done to the instructions you would have no problem getting the section out and the head off in less than 30 minutes. I've done it as have dozens of others who have the kits.
Sorry to decline, but I did these for the community and a wonderful old fella that only rabbit hunts now days.
Best Regards, Gordon
