A good source for pushrods?

I aquired a set of Mantons, they are out of Elsinore area? These beasts were tapered they were so big in the cross section. Sold them asap as they were way overkill for my B, My slant rods are working fine for my LA flat tappet app, stock roller material doesn't take to 300lb seat pressure. If the weakest part of the valve train is the pushrods, you are doing it right as they are the cheapest bits to replace. Bustin a T&D roller rocker because the 1/2 tapered cro-mo pushrod popped out the seat isn't the way to play.
