    Gee, this turned into a bitch fight, I only asked if he lived at a wreckers hence he has 3 phase..

    Yes my spelling is not good but you seem to understand what I'm saying, all I want is to help people and give them another avenue its then up to the OP either to take it or leave it..

    And yes VC I did lay into VIN as he was coming across a bit aggressive, then I changed my point of view once all your close neat group started on me, If you cant handle the backlash then don't dish it out. AS the mod said ignore and move on all this bs can be avoided if your gang just stop starting things and protecting each other putting your noses in. We are all not perfect and said things that didn't help the OP question just like your oil pressure hell VS lover saying a Intake manifold gasket is the reason for a rough idle when it has no effect bar oil in coolant or vice versa. I said many of times unless the car is in your drive way its just speculation assuming the issues.
    Every bit of info can lead to solving a problem right or wrong, bottom line taking it to a mechanic is a best option on most cases you can spend triple the amount of money replacing unnecessary parts.

    I'd chop stud off drill hole just to fit HT nut & bolt...quick & simple solution.

    Then if it bends or breaks easier to replace next time although should be fine as I've done that on IRS cars with stripped out lower shock bolts when some doofus rattle guns them in tight.

    Yea have to agree.

    And while I suggested welding I am happy to admit the best and probably cheapest is drill/tap/and bolt, but of course if the op does not have a drill and bits, or tap or experience to use both then a trip to someone who can do the job may be the go.

    I ended up doing the job today, quite time consuming but i got there....
    3/8th Rod with a few nuts, 8mm Drill bit (which was a tag small) 3/8th Tap...
    Due to the 8mm drill bit (which the nut n bolt place said was correct size to use) being a bit small, i had to ream to hole a little to be able to cut a thread.
    But all done now...

    Lets hope Phillbert didn't get the rod from bunnings that would most likely be 4.8 the fact he said its 3/8 not 10 mm would probably give it away that its not our favourite cheap rod in 3 pages surely it was mentioned to get a high tensile bolt it never hurts to check ?

    Because I've never come across all thread in high tensile at any hardware store, I hope he talking about a threaded stud than all thread. And Bunnings do sell 3/8 all thread ( rod ) for 4.50. To get high tensile all thread would cost more than a bolt up to 10x as much.

    LOL, I bet you buy all the replacement bolts for your car from Bunnings.

    Very easy to get some imperial grade 5 threaded rod from any fastener store.

    Depends on what purpose, high tensile don't go to big in size in Bunnings, I can usually get the champion bolts in Supercheap again depending on the size, the west side of Melbourne is piss poor for fastener stores so I buy on line if I need a pacific size and tread type, oh grade 5 pmsl.

    I won't quote all the dribble but as said i got the rod from a Nut n Bolt store which recommend that piece of rod.
    The rod/stud on the end of the shank does not take any weight, all the up/down pressure is on the shank itself.
    The rod/stud is only to stop the shock from slipping off the shank. I had is held on with a zippy tie until i fixed it yesterday and it didn't move a bit, not that i drive it very long in that state lol.

    Well done Phillbert. Glad you got the job done, let us know how and why and avoided responding directly to the warriors on your post.

    Good maybe mention what grade rod, its done now sounds like you done it the hard way when a simple 100mm 8.8 bolt done up tight in your new tapped out thread with some tread lock and then cut off the hex end would of made things much easier for your self, washer and locknut and your done. Just remember if its only a mild to mid strength rod a person may still over tighten it and snap it off again that's why its best to go high tensile not because it doesn't bare weight.
    The workshop manual says to torque the lower shock bolt to 105-125Nm, might of been best to tap it out and just use a 8.8 bolt instead of a stud and nut. Next time if need be, cheers.
