I need studs!

Put it back in your pants. I'm after some metric studs to mount my Holley progressive with an aluminium spacer. the ones I have are too short and I have no idea where to source studs from.

Can someone tell me what sort of place I can buy them from?

Thanks.

go to your local hardware and buy a meter of allthread (booker rod) then cut them the size you want,either that or a fully threaded bolt to the length you need and cut the head off and dress up the end 👍

Your other option is to go to an exhaust shop with your sizes and purchase them ready made.

Hardware store threaded rod is usually pretty terrible low-grade stuff and made of cheese. I'd buy studs from a proper engineering supplier like CBC or someone like that.

well it is only for holding down a carby,and he lives out in the middle of the country,didnt think of exhaust place grumble🙄

The hardware store ones are usually imperial thread.I'd have to tap and helicoil probably if I used them.
No exhaust places for about 100km. There's a store that sells ...stuff. various bolts fittings, some tools, wiring things, motorbike, generator etc. parts, welders, camp fridges and whatever. Possibly them. I think there's a tractor supply place,a couple of small hardware stores, a plumbing and miscellaneous place, and I don't know what else. help me here are type 4 exhaust studs larger diameter on one end than the other? if not they may do it.

Once I get these studs sorted and pick up the manifold gaskets from the mechanic I'll be set to install. I wasn't game to make them myself because the coolant runs like 5mm away from the manifold. Yes coolant. Check the sig.
I made up the carburettor / spacer gaskets this arvo. Only took me a few minutes. Fit great too which was good because there was more guesstimation than I'd like to admit.

Just for the sake of running up your monthly data count:

Here's the spacer. I pulled that stud both because I got things stuck and I wanted a length reference.

Here's the manifold with carb and spacer sitting on it:


Spacer and quickie homemade gaskets:

OK what size threads do you need,if they need to be stepped what size each end and what length.I have some T4 O/S exhaust studs,from memory they are 10mm one end and 8mm the other,not sure of length.let me know what you need and I may be able to help. Cheers Les

I was wondering about exhaust studs because I have four interesting looking paperweights sitting around.

The stud size should be obvious to me but my head is all cloudy from the pulled tooth. I'll dig out the thread gauges and vernier tomorrow and check it empirically, but at a guess I'd say m8 x 1.0 by maybe 5cm long.

It feels like I'm re-covering so much ground here. I got so far with the type 4 and hit a massive impasse. It's bad when the path of least resistance is an engine swap. So now I'm catching up in some ways and way ahead of where I was in others. At least my 7 year deadlock with that motor is over. Still have it with the hope I can fix it, but that's going deeper into the rabbit hole...

Should be interesting to see how the EA81 responds with the jetting. I got the carburettor set up fairly nicely for the type 4, and the EA81 really isn't such a different motor. No matter what it has to be better than the senile Hitachi that is on it.

Mechanically speaking the carburettor and a damaged brake line are the biggest hurdles I have left. The steering box is a bit of a ?, and the rest of the issues can pretty much be fixed with the grinder and MIG. lots of minor to medium things to address but nothing I can't handle, I hope. It's just silly issues like these studs that get me all hung up. Thanks for the offer of help Les. Much appreciated as always.

Standard 8mm thread is 8x1.25.
Try some old engine or gearbox studs if you cant get to a shop.

I wish i had a spare gearbox! Anyway I asked around today and found that the mechanic has a stash of studs. Got some nice uneven threaded ones which were perfect for the job. I did however discover that the carb base holes had been drilled a fraction crooked which made getting the spacer and carburettor on a bit awkward (understatement) but it's assembled now. It'll have to be pulled apart again but I won't bother until I get a thermostat and gasket to finish preparing the manifold. I also need to plug some of its vac lines and remove a useless gable guide bracket. The engine bay should look a bit cleaner after this at very least. The engine should run better too.
