So I’ve managed to obtain this strut brace kit, the mounting panel is on the way, but I haven’t got any of the bolts that bolt the brace itself to the mounting bracket on the firewall, or the bolts that join the center section of the brace to the left and right bits that affix to the top of the shock mounts.
This particular bolt seems to be the tricky one… The rest of them are all standard sizes.
Would it be possible for you to unbolt the one I’ve circled and post some pictures? If you could take measurements of the actual bolt itself too that would be amazing…
The fitting kit for it is like rocking horse sh|t, not helped by the impossibility of finding part numbers!
Happy to do that in the morning but I don’t have vernier gauges just a Stanley tape measure, you are very welcome to come and take a look if you are close by … Huddersfield
I dropped by MX5 City earlier and they measured the internal diameter of the circled bit…
They came back with 11mm which I find odd… But I need to know what the bolt itself looks like. I reckon it’ll be collared, but that also doesn’t explain the tolerance gap on the lower section… Just can’t get my head around it!
Yeah I live near Pontefract so depending on whether your photos answer the question or not, I may take you up on that and have a ride over!!
For cosmetic reasons I removed and repainted the brace parts then fitted new nuts. I bough a selection online, high tensile steel. I don’t recall exactly which but were nothing special. Just checked, they are a 13mm socket
Just another comment on this, I have a small local firm that sells fittings and hardware etc. The guy on the trade counter checks what I take him, measures and identifies the item and I generally I get a handful for a fiver. Never been wrong yet and I’ve now built up a substantial stock of odds and sods myself. Surely these places must exist everywhere??
I’ve slowly replaced most of the original nuts and bolts with new as I’ve gone through the car. He always asks what it’s for, so I get the right product. Stainless for cosmetic, tensile where stress is involved.
So here are some pics that may help, and confirm 12mm socket as I have just taken it off for the photos . The centre section once nuts removed is a very loose fit on the bolt/stud not sure if this is where you are concerned. Hopefully the pics can help
I can’t find my transaction details, but search M8 bolts on eBay, I have used two suppliers, boltworld and Kay’s, both did the job. They have vast ranges listed. Btw, that wasn’t my pic, mine are painted true red…
