First off, apologies for joining only to sell - my car interests lie elsewhere - and thanks to the mods/admins for allowing me to post.
I secured a large quantity of car parts in late 2011 for my own interests, amongst which were a considerable number of parts for other vehicles which I need to move on. There's perhaps not many 126 new spares around, but if they're any use to anyone on here I have for sale:
A remanufactured starter motor (LRS740) which is listed for Fiat 126 BIS 0.7 1987-95 and is rated at 0.6kw. £15 please but watch out for postage as it's heavy!
I also have a set of brake shoes - Mintex MFR3 for the 126 (and 500) up to 1975. £5 please!
Hope these are useful to someone!
