Bill - as I said the other day we (Autoglass) don't have one in my branch and it's not a stocked item, but we can get them, as I have had to fit new ones before and they have been ordered in for the job.

We use 4 digit codes for car identification (for example, 3552 is the code for a mk4/5 Fiesta) and both the mk3 and mk4 Escorts are the same, code for them is 3544 (IIRC). Every bot of glass is the same (except for the mk3's available with opening rear quarters, and mk4 rear screens available with radio antenna), the only difference is the colour (clear/bronze for mk3, clear/green for mk4) as are the rubbers for all glass too

Hope this helps chap
