What size threads would that be?

Jimmy
makes this up on a regular basis. I got this setup from him and he uses quality parts and ships fast. He's a member here as well and recently made this same post here but I couldn't find it. That's a fair price. I made one up myself and had to search to find the parts I needed. Ordered the parts from 3 different vendors & the end price was only a tiny bit less than he charges. Save yourself the hassle & get one made up already from Jimmy. JMHO
