I need to replace a timing belt cover on a MK1 Uno Fire 1L. There is a number on the inside of the cover but I am not sure if it is a part number or not. The number is A255 and directly under it is 4731/1. Does anyone know if this is a part number or not. If not, does anyone know where I could find the part number of the timing belt cover.

Thanks.

Go to the nearest scrapyard.
The part number is:
843-2525-846464-2358-26837
(T-H-E B-L-A-C-K T-I-M-I-N-G B-E-L-T C-O-V-E-R)

There are no UNO's in the scrapyards where I live.
