What size/type plugs are used for the ends of the rocker shafts? I measure .525" at the end, but there appears to be a step down where the plug sits. I've googled for .500" plugs and there are several types. What is the correct plug to ask for?
Thanks, Gene

I have the shaft on the way from Rock Auto. I had no way of knowing if they already have the plugs and, as inexpensive as they are, was going to have them on hand just in case they didn't. I can't find them in stock anywhere in our capital city. The shaft is to be here tomorrow per USPS tracking, so I'll just wait and see. Thank you for sharing your knowledge!!

These Shafts are another Y Block Item that is available by simply ordering. I remember not too many Years ago you had to hunt around for NOS Ones.And they were not Cheap when You were able to find them.
