I'm sure you're aware that stress is applied horizontally onto plate, therefore they didn't have to make it thick. I'm with you on the bolts, why not have regular 10.9 grade that can be torqued numerous times without issues.

Coming back to this. Anyone who found alternatives discover anything to report?

Are those Dodge bolts good to use? Do they fit the stock nuts?

While I appreciate the fast response. I am not comfortable re-using the old bolts.

Then, out of curiosity, why are you looking for alternatives to the factory bolts? I realize they are $75, but if you are worried about something, those bolts were designed for the purpose.

To me, any decent replacement grade bolt would do the job. I'm guessing these are stretch bolts/TTY so that they will shear in the case of an accident... so you may compromise that a little, but if you hit something hard enough for that to be an issue... other things might be more concerning.

Personally, I plan on re-using the stock bolts... :dunno:

recently had engine replaced, then the transmission went out about 1k miles later.

replaced tranny, and car was great.... Then a squeak developed. slight at first, then horrible. I thought it was the front differential, so I changed the fluid. Helped some, but still there.

Then I realized I had read somewhere someone saying they had a horrible squeak if they reused the old reinf. plate bolts.

so, bought some new ones, reinstalled to spec and...voila. No more squeek.
The old bolts were clearly no longer straight.

so I think after 3 removal/reinstalls, they are done. Check the bolts carefully: if you see that they are no longer true, I recommend replacing them.

so yes, despited all the engineers ;) in the thread, the bolts do make a difference

I completely believe you that after 3 uses you can run into issues. And thank you for posting the squeak can be caused by reusing the bolts. Others who have reused them once have reported being okay... so as you say, inspect the bolts and reuse knowing if they make noise you will have to replace. :thumbup:

Sure is, reminiscent of the $90 wiper blades owners used to have to buy directly from BMW for the e39. BMW got in trouble for that if memory serves...

My only concern with reusing them is that they're probably "tired" and more likely to snap, not necessarily during reinstalling but later on during driving. But, you just might be right about not worrying about them.

Just to play it safe I'll probably go with 10.9 grade M10X60 from Ace Hardware of all places. It's about $25 for 6 flanged bolts and 6 flanged nuts. I've checked online and some local places and $25 is about cheapest for 10.9 grade.

Obviously, I'll check first that 5mm extra is non to long but I'm almost certain that it's not.

Would these be torqued down the same way as the OEM ones or maybe just stop at 41 and ignore the added 90 degree turn?
