Thank you, Al. I’ll make a couple up when I find suitable material.

I just went to the workshop and measured one.

You are welcome Seadog, I forgot to mention that the thickness of the material is 0.5mm.

Thanks again, Al. I’ll post my results when I get to the job.

Our welding wire is supplied in these black polyprop tubes, they are 1m x 40mm & would probably be ok to make the tubes from, very easy to cut & heat-form the flange, trouble is, we throw them away!!

Hi Modelman, that should work ok.

I've made a few sets of these using industrial plastic shim stock. This is used for leveling precision machinery, so it's very durable. AccuTrex Practi-Shim is a popular brand here, and their yellow colored stock is 0.020" thick, close enough to 0.5mm. Thicknesses from 0.0005" to 0.030" are available. You can cut it with scissors, or a good blade. It comes in handy for many purposes, including reducing swingarm side play. Regards, Chase

I got around to fiddling with my Type II front forks today. I found the main bodies of the spring guides on each leg, but the flanged/tab portions were gone. I found most of the broken tabs mashed into the top of the seal support in the chrome lower case cover. It appears that someone installed them at the bottom of the spring instead of the top. Flattening one guide out, I found that it measured 104mm wide. Then, using the height dimensions posted by AlanW (thanks again), I made one new guide up using gasket material. 95mm high, with the tabs 5mm long. I simply counted the number of tabs on G-Man's photo - 21 - and cut that number of tabs evenly spaced. The guide came out well, but I'll need better material. I think I'll get some shim stock, as Chase recommended. Results below:
