Part no. needed urgently! / Removing fire ring on cats

[dest]

Does anyone know of an equivalent part that can be used for the front fire ring on ABY cats?
We cant get the old ones out?
Audi dont have any in stock, the part is 443253137D

Cant get them out? Most exhaust places like kwik-fit etc will have a stock of generic seals, albums lists them as 55mm size. Only thing to watch for is the shape of them, some have a 45 degree taper egde, some are radius, some are flat.

431 253 137 A
073 253 137 A
477 253 137 (AUDI A4 11/94-)
855 253 137 A

These seem to have the same dimensions as the first part, as they have the same non-oem part no.

Turns out it was the rear ones needed, so is a different part number. Had to order some in for tomorrow. 14 quid! each
