Gearbox identification help!

Hi Guys
Need to change the Layshaft bearings on my 1988 Santana 90. I am just trying to find out which gearbox i have so I can order the correct parts to reduce the time the truck is off the road. There is a serial number on the left hand side of the Gearbox thats seems to say - E / FRC2677-CEA

Any ideas which this one is, and where to get the spares?
Will
