We have a 1994 21Z 963 we bought a few months ago. The machine is really clean and low hours. We have a 2nd 963 and they both have GP buckets. We do a fair amount of farm demolition work and tree stuff. Considering adding a 3rd valve to it and a 4N1 if we could find one. Any idea what it would cost to add the valve and a good resource to look for buckets is appreciated. Thanks!
Have seen two offered on Machinery Trader for Cat specific, look for 'MP' bucket in searches. As to the third valve check for a p/n with your cat parts rep against the s/n and do a parts search on Mach. Trader may do some good that way.
