Seat Belt Replacement

Hi,
I'm trying to locate a rear drivers side seatbelt replacement for my 1999 Trident (the spring exploded out of it). I called Autosleeper and they couldn't supply but the guy in the service centre said that they were made by Securon. Further investigation shows that Securon no longer make an exact replacement i.e. length, retractor position and adjustable buckle length webbing. Anyone else had a similar issue or found a solution? Help appreciated!

There's a load of different Securon belts on eBay, have you looked through the various models. Is this for a rock and roll bed?

Thanks for the reply and yes it is for a rock and roll bed.

There appear to be two rock and roll seat belts available from Securon , the 507 and 5051, have you checked those out?

Both the 507 and 5051 have seat loop guides rather than the pillar loop I need. I ordered the 500W but the retractor doesn't work in the horizontal upside down position required. I'm considering buying the 264 with adjustable retractor angle but this is 50cm shorter than the one being replaced.
