Greetings, Arnold friends, well the weather here in England is improving, so i have decided its time to fix my windows, i have seitz windows all round and i have located a source here in England, now my problem is that the numbers on the windows dont match the new ones so before ordering them i was wondering if any one else has replaced windows and what numbers you used for replacement, i think that they are S4 type now but i cannot seem to work out the models i need, i need to replace the large rear window and one side window. so if any one has the right model numbers and size's, i would be really grateful if you could let me know them please. it a RM35l thank you in advance Jeff
