Reliable vendors:
Most parts I have found cheapest and quickest delivery from Ebay.

Most cab trim pieces are attached with flanged button head cap screw/bolts with a T30 torx. They hold water and are mostly all destroyed with rust, requiring to drill them out. Unclear how to easily replace the weld-on nut under the steel floor plate.
Replacing them with allen head now - tentatively M6 x 1.0mm thread x 25mm (JCB p/n is 826/01768)
For changing hub gear oil, raise entire machine via bucket + outriggers, then rotate wheels where oil drain is at top half.
Get a 5 gallon bucket and bungee straps, and place bucket as in picture:
Remove drain plug, then rotate tire so drain/fill hole will drain into bucket. When bucket is getting full, it can stretch the cord - so after the initial deluge of fluid I usually swap buckets or empty the bucket into another.
