Help. Rubber mat

Can anyone help? I am looking for a rubber mat for the cab of my AutoSleeper Trident 1999. Has anyone ever bought one and what am I looking for. Will the VW T4 mat fit. It looks the same but is it? Any advice will be welcome.        
Thanks in advance.

I thought the Trident was built on a T4.

It is. I phoned auto sleeper up and a woman replied - didn't know We put carpets in. Then I phoned car mat shop and a woman replied - don't know. We do vans. I am sure the Trident is a t4 and now you have said I will phone the mat shop again and ask to speak to a MAN. Sorry ladies

plenty of 'T4 cab mats' to be found on ebay.

just make sure you choose a T4, not a T5 :)

Thanks Johnnybee but it's not that easy. If you look all the mats are different designs. There is only one the same style as mine and that is carpet and I want rubber. I have searched eBay. It is very difficult and guess I'll have to phone a few more shops until someone will say yes I have one that will fit.
