I just spoke with Richard Oliver, (The RO of RO Jett) and He said that Dub has been out of town and is now likely trying to play catch up.
Richard reminded me that Dub is pretty much a one man show these days and sometimes when busy just can't answer the phone instantly. However, if you leave a message He usually will get back to you in a reasonable length of time.
Call and leave a message with some details of what you want, which is what I always do, and He'll call you back!
You can't go wrong with His engines. I have 6 of them and they run with the very best!
