Hi, where I can find the Sierra diff long bolt M12 x 208 mm?

The only site that seems to sell it is this one:

Cosworth Rear Diff / Beam long bolt - new

even if there isn't any technical description to confirm it is the proper one, but it doesn't ship abroad

You can use screwed rod

Threaded bar as above,if you can fit it in.tight on some cars,including my Mac1,due to it fouling on chassis.

I use two allen cap head bolts inserted from the inside out.

I used 8.8 HT threaded rod, works fine, and you can cut it to any length.

M12x200 or M12x210 is a standard bolt size easily enough available from engineering suppliers as normal HT hex bolts. Alternatively cap screws or stainless types are also available.

Thanks to all. I will try to find M12x210 and threaded bar as alternative.

I found one on a 125cc scooter, the hinge for the engine, fitted mint!
