Yep, you can get them from Hughes or you can make them yourself, I had some old 273 pushrods and I just cut one and taped it to 1/4-20. I think that if you order pushrods from hughes he will not charge you. Dont forget the adjustable lifter so you can get your preload correct.
I think mine was a Comp Cams unit . I got it from Summit. They send it fast (I needed it fast) Are your pushrods a ball and ball or a ball and cup. Measure your present pushrods and order the correct length checker with the correct ends. Mike
