went threw and got all the bolt part numbers for rocker covers, primary cover, cam chest cover, starter transmission side cover,transmission to engine lifter covers, and derby cover

if you want 6 point first 3 digits are
1/4 621
5/16 622
3/8 633

I went 12 point

3/8 you will need
615-2000 1 package
615-1500 1 package
5/16 you will need
612-1500 1 package
612-1250 1 package
1/4 you will need
611-1500 1 package
611-1000 3 packages
611-1250 5 packages
611-2000 1 package
611-4000 1 package
611-0515 1 package
611-0750 4 packages

I got mine from Jegs 270 bucks for all cheaper if you go 6 point but not by much

 

Thanks, that will be helpful information.

 

Does APR have a corrosion resistant black finish? Need to update my signature. I have a 2018 special now which is of course blacked out.

Do you have a list of bolt sizes needed to do a black bolt conversion?
