I found a site selling grade 5 ones, I'm not sure how expensive they are though.

Mcmaster-carr. The ones that you have are probably grade 5 not grade 8.

Mcmaster-Carr will have a much better selection.

I would just like to mention one thing - not all bolts you get from vendors are high quality, I don't care what anyone says. I was tightening a new trailing arm bolt and the threads got stripped and the nut threads pulled out. I was using a brand new, just calibrated torque wrench and I had the shims and trailing arms wedged in the pocket like they are supposed to be. I have to replace the bolts now - I'm going to drill a hole in a long grade 8 bolt and use that with a castle nut instead. So, if you think just going to the vendors for bolts is good enough, think again. I buy all my colts from an industrial fastenal here in Calgary, grade 8 and plated. This is the main reason I brought up this subject - some of the vendors out there are charging a crap load of money for fasteners that are cheap quality.

i agree whole-heartedly.
but, as a word from the sunny south, do you think that the freezing cold, arctic, bone chilling, god awful, sub zero temperatures you have where you live weaken the bolts?

If you get a grade 5 carriage bolt with a really long shank that isn't threaded, you could use an appropriate sized fine thread die (from a tap and die set) and make the correct fine thread one...wouldn't take to long either. I've made my own bolts before and its really easy using a fine thread die...using a coarse thread die by hand takes for ever though because of how deep it cuts.

The problem is I don't like reusing old bolts. I've only reused two bolts on my resto so far and they were the massive ones on the front caliper bracket...the rest of my stuff is all grade 8 and plated.

I just talked to Fastenal - the guy I talked to said that grade 8 carriage bolts are very uncommon and that he can get me grade 5 carriage bolts with fine threads instead of coarse. I will go home tonight and figure out what size I need and I will try and order the correct ones tomorrow - if they have what I need, I'll post the part number so everybody on the forum can get the correct ones.
