Thanks for the links guys... but all to no avail im afraid, closest i could find was the parts manual which is less than useless to me. I knew it would be a longshot, but i had to ask here.. i had nothing to lose! Anyway after a LOT of searching and phone calls, no good..
I had a feeling i'd be biting off more than i could chew taking this on.. one of these days i'll trust my instincts
