How many rollers do you want.
When replacing only one or two you should measure the existing rollers and get a second hand one about the same dia...
I think in a recent post , Conservation bulletin ???????? Had a chart on roller sizes
Let me know what you need should be able to find something here.
will send you a PM.

New track roller diameter is 8.75"
100% worn is 8.00"
New lifetime roller assemblies if you can find them
Single Flange 8H3863
Double Flange 8H3936
All are out of production now but there are still some out there.

Old Magnet, wasn't there a difference in bolt hole sizes in the collars? ...5/8" to 3/4" later? If you had the 5/8 bolts you had to use a 'filler'.

It's been well over 30 years since I bought any rollers for a 3T.

My info on roller bolting isn't the best but based on the 4F262 lock that they used the bolt diameter is the same size throughout the production run. May change when trying to adapt later rollers as you say.

Does that lock carry on through the 17A series?
I remember something about bolt sizes for the rollers.....I don't have senior moments any more, I have senior days.
