    Just making sure these two sets of bolts are not meant for the same location. I would hate to order both and realize that the bolts go into the same place and serve two different purposes.

    To fix "Cobra Clunk"

    To clear wide wheel/tire combo

    I'm guessing that the FTB kit is installed in the "front" of the IRS and the MM kit is installed within the wheel well area but just making sure.

    Thanks,
    Dan

    You have it correct. The top bolts you listed are for the front/lower of the irs and the bottom bolts you listed are for the top/back of the irs

    You can probably buy those two bolts, washers, and lock nuts for 1/4th the price at your local hardware store. Someone posted the exact measurements, they're 4 1/4" including the length of the head, if you're just measuring the shank they're 4".

    Those bolts are like the same price if you buy them local. Most of the time and in my case The stores around me didn't have a lock nut that size so I had to use a lock washer and normal nut. No big deal but just something I noticed.

    Here is that thread you are talking about

    Yep. Just buy em from them.
    I decided to buy 9/16" bolts from fastenal and it ended up costing more since I had to buy a pack of 4 bolts and nuts and washers the same way. And the fact they were grade 8 as well.

    I went to the local Ace Hardware and bought 2 grade 8 bolts, 4 flat washers, 2 lock nuts for $9.29 with tax. They were out of nylon lock nuts so I had to get the all metal ones, which added an extra $1.00 to the bill. So half price bought at the local hardware store.

    If you go to a place like Lowes/Home Depot that sells individual prepackaged bolts/washers/nuts expect to spend north of $16.00.
