Is that Pushrod cup the correct size ?
Might just be the pic and shadows but it looks large for that adjuster ball end
It's the right diameter (3/8"), but the cups were manufactured pretty deep. About .165 where the old pushrods were about .140. I took the cups down to about .145 and that got me very close. I'll be adding some washers next and see what that does. I don't mind doing a little grinding here and there so long as I don't pop through a casting, but if a washer gets the job done, even better. I should have been a little more careful with ordering, but honestly, even the old pushrods which were way too short were still pretty close to clearance issues.
As always, I appreciate the help and thoughts!
