Pushrod Problems?

Smith Brothers is a reputable shop for custom length pushrods. There are other sellers also
To do it right, you will need a ‘push rod length checker’ basically push rod approximately the correct length with a threaded section in the center for changing the length by screwing it in or out. They are available pre made or if you are handy with a tap, pretty easy to make using one of your existing push rods, use a fine thread bolt.
