Camshaft bearing bolts help please
 

I am doing the heads and timing chain & guides on my 1987 420 sel 4.2L
in taking the engine apart I found that the engine has been worked on before and some of the camshaft bearing bolts where stripped out heads
I had to use a grinder carefully remove the heads in order to remove the cam assembly.
I have looked all over for the net short of going to the dealer to find these and I found every other bolt pertaining to the heads except for these. can anybody post a link to wear I can get these I need the short ones on the intake side thank you.

Order MB part number 000912-010017 5 bolts @ side
