I couldn't find a partnumber anywhere for the camshaft brackets. I imagine they're probably sold with the heads but I'm hoping to get two additional ones. Can anyone help out?

I guess Bearing Cap is what i mean.

and this is the one i need

 

more and likey sold with the head if you replace one you need a macine shop to check the line bore. i had to do the same thing on a 240 that i use to have.if the bore is not true it will mess the cam and possibly the head.
