SU's Nuts & Bolts Questions

[Go240Zags]

Hi, I've travelled to the big city of Spokane to watch Gonzaga beat St. Mary's and just down the street from my daughter's is an Ace Hardware, that, unlike my hometown store, stocks metric nuts and bolts, and other hardware in Stainless Steel. Since I left my carbs at home on the kitchen table, I am hoping you guys can help me with a few sizes for the odds and ends I'd like to replace with SS hardware.

I need the size of the nuts that retain the SU carbs to the studs. Looking at the nut I thought maybe a size 8, but then looking at some auto studs I started thinking size 10. Which is it? I don't want to pay for the wrong thing as they are quite a bit more than for non-stainless.

In addition to the nuts, what size are the pan heads that that hold the float bowl lids on. What about the bolts for the assessories on the balance tube and the ones that hold the heat shield on. I know some were 5s with a .80 thread and others were 6s w/ .100, but can't remember which were which and how many and how long. Any help I can get on these and any other thing I can pick up while I am in town would be appreciated.

Oh yeah, while I'm here, what size are the holes on the bumper if I want to fill them in with SS bolts, rather than putting on the upright bumperetts, or whatever they're called?

Thanks in advance for your response.

Anyone? I'd like to pick up some of these items before I have to head back to rural America.

I can't help you with the sizes, Gary. My car is across town waiting for some more work and a new battery. But, I'll mention that the nuts that hold the carbs to the studs on the manifold do not appear to be "full-height" standard nuts. That is they are not as thick (tall) as normal nuts.

EDIT: Come to think of it, I'm *pretty sure* they are 8mm X 1.25 (same as the manifold to head nuts/bolts

Correct, they do take a 10mm wrench though.

You're right Carl, just went and and looked. Been awhile since the ZT carbs went on.

Thanks guys, I'll check back and see if there is any other info on the bolts later. If I would have been thinking I would have brought samples with me. Things like lock washers and washers are easy because SAE stainless works fine. Someone sent me some allen head screws for the domes in stainless once. They look nice, altho not very original to the carbs. Might see what I can find at the local wrecking yards as far as 240 parts while I'm here as well.
