hi. new to the forum. I have an 89 F150 4.9 that I'm in the process of restoring. I had a tough fight getting the intake manifold studs and ended up having to have them drilled out at a machine shop after breaking 4 of them. I'm in need of replacement studs but I cannot find any at my usual sources. Per the Ford manual, they are 5/16-18 x 2.505. Does anyone have a vendor that you can recommend to find replacements? I've tried NAPA, AutoZone, Amazon, eBay, Summit, etc. etc. Thanks!

You could always trim these, or just let them be a bit longer. https://www.fastenal.com/products/details/11126636?r=~%7Ccategoryl1:"600000%20Fasteners"%7C~ %20~%7Ccategoryl2:"600169%20Rods%20and%20Studs"%7C ~%20~%7Ccategoryl3:"600171%20Fully%20Threaded%20St uds"%7C~%20~%7Csattr02:%5E5/16"-18$%7C~

I bet your local hardware store has them.

I bet the machinist who drilled them out can get them. What exactly are "your usual sources"?

Thanks all. I got them through Grainger. As mentioned in my first post, my "usual" sources are: NAPA, AutoZone, Amazon, eBay, Summit, etc.
