    Hey all, I just picked up a 2010 Tacoma V6 which requires.... Exhaust manifold work... Shocker right?

    I'm planning on keeping this rig stock (for now) so just putting on some stock headers for now to quiet the rig up (she's loud hah)

    So my question is, local dealers have backorder on manifold bolts\nuts. I've been searching around to try and find the thread and stud size...

    I found M10 X1.25 42MM & 8mm x 1.25 no length...

    Anyone have any idea what the thread and length is of the studs? I'd like to see if can find a lot somewhere vs waiting for the dealer to get stock.

    Thanks all!

    Thanks! Yes, those are the back ordered items locally here. Has anyone found out the tread of the block? I see others using ARP kits on aftermarket setups but finding mixed info on the thread size

    Also found this tread that might be helpful:
    How to remove the exhaust manifold studs?
    It shows the ARP 434-1301 kit for LS1 is the persct size for 1gr-fe too according to the OP in that thread.
    This post goes over the length.
    ARP Head-Header Studs
    But you might want to read the whole tread as someone mentions they didn't work for them when trying to use them with oem manifolds.

    Thanks! The redirects for dezod didn't work when I found the posting originally to try and compare to the other posting listed above which was giving me the conflicting sizes.

    I think from the gist of it, you can use the arp for aftermarket headers but if using OEM you will need to find ones a little longer for the top bolts. Can't say for sure b/c I don't think I found anyone saying they were using the studs with stock headers.

    Hah yeah that's the issue I'm finding, all I'm after is the thread type on the block so I can see about finding alternative options for factory replacements from Dorman for example

    Well I will say I read in other threads that the only options people have found were for OEM and ARP....No luck with finding them other places like autoparts stores or fastenal. Best of luck.
