Upgrading lug studs?
 

Well I'm pretty new to the site and diesels in general. I have a 93' D250, clubcab, cummins, getrag with 205k. I have questions galore. I've found a wealth of knowlage here, but I'm surfing on my phone and navigateing is slow.
1. Has anyone upgraded the lug studs from the 1/2" to 9/16"? Looks like there is enough room for beefier studs.
2. Is there a good resource to show a first timer how to reseal the injection pump?
Those are eating up most of my free time for now although I have many more.

Thanks for having me.

Your truck has 1/2" studs ???? Normally these trucks come with 5/8"
