Ultra shield are very reasonable, butler built is hard to argue with as well. Literal racing products in fortville keeps the ultra shields in stock, that’s where my driver got his.
If you want a Butler definitely go through KRJ. Learned my lesson going through Butler direct at PRI. They are not good about being done anywhere near on time and aren’t sorry about it. Ken at KRJ is awesome to deal with and will make sure you’re taken care of.
