CV boot foul up

[vanny]

Tried to do the inner boot on the short shaft today. All going semi well until trying to fit the corteco replacement boot. The box has the AS part no N45058 which is what i want 'CV BOOT KIT-INNER BX ALL (EXC BX14>RP4192)' the corteco number is 329359B.
Having assumed the part supplied was correct i started putting it on BUT its to short and the CV end is about an inch too large (looks like its for a Xantia at a guess?). In desperation ive tried fitting an outer boot, no joy.
Can someone tell me what the Corteco number should be?
This is just briliant timing given that im meant to be doing 300 mile trip into and around birmingham tomorrow, no time to wait for AS to 'try' and get one here.
