Its been a while since I was last on having bought a 'barn find' French registered 1985 Renault 4 TL. I'm at the stage of recommissioning and finding the various models a little confusing. My best guess, based on the tag in the engine bay is that it is a Billancourt (B1B D 7/07) 845cc engined model 1123 with all round drum brakes. The date of first registration is 06/09/1985 (carte gris) but there is a Renault sticker next to the vin plate which states 1986. Even trying to locate a basic service kit has been confusing as there seem to be a variety of different options for oil and air filter based on the physical size of the air filter and even the thread size for the oil filter. Can someone confirm that I have correctly identified my Renault 4..that would be a great starting point. Thank you
