Can anyone tell me the number for what is often referred to as loctite plastic gasket in the manuals or it’s modern replacement?

I’ve seen:

567 (low strength thread sealing)
565 controlled strength thread sealing

Or is there another I need to be looking at? Or is plastic gasket still available? The use of such in the manuals is around threaded areas

Pulverised Vinsol resin with some other stuff (Perchloroethylene, etc.) according to the data sheet:

Yes, it was only meant to be an example of the actual product, I wasn't suggesting that you buy it.

Loctite sealant technology does seem to have progressed since "Plastic Gasket No.68" was available.

Before rather than "after" as Norton Villiers became Norton Villiers Triumph (NVT) in 1973 (and when they dropped the NV green globe logo) so couldn't really have been manufactured later than '73.

The 064208 Loctite Plastic Gasket pack was mentioned in a '73 Norton factory service release.

Wellseal still seems as good as anything else in my opinion.

I don't think you'll be disappointed by Loctite 515 or 518. I worked at a tractor dealership. When separating the engine from transmission or the trans from the rear axle, 518 was required by the factory service manual. Anything less would allow flex which would break the seal and then oil on the floor. It's strong stuff yet it is not difficult to disassemble or clean off the surface. I use it on my bikes. You can use it alone or with a gasket.
