400ex hot rods crank / main bearings

[MUDDIN400EX]

ok so I am pretty much rebuilding my entire 400ex engine. I just bought a 400ex hot rods stock crank. Now i found out you have to use hot rods main bearings also.. is this true? if so, where in the heck can you find these things at? thanks please help asap

It should be the same bearing as the stock crank. stock bearings should work.:)
