I recently ordered some new interior door handles, I went by the Franzose catalogue, ordering 4X79MM tongues. As indicated for my model year. My car being Australian, for some obscure reason requires 73mm tongue in the rear, and 90mm tongues in the front. Apparently this is an Australian quirk, worth making a mental note. Not sure if anyone knows why, but a pain to put right if you realise the error only once the handles arrive. Now have new handles with correct length tongues. So I can finish the job I started 6 weeks ago........ Among others.
