anybody have a good lead on compression test fittings for the GP holes? i have the gauge and all, but i dont have a fitting needed to screw into the hole.
what compression numbers should i be looking for on a good cylinder? what difference would be considered questionable between cylinders?

Harbor Freight Sells a complete set at a resonable price. It has the Glow Plug Fitting and the one that goes into the Injector. It also will do some later models and other Makes of Engines.
Detractions to the kit are that the Injector Adapter has an area of hollow space that throw off the reading slightly to the low side.
I have read one account where 2 gauges from 2 different kits did not record the same pressure. (Since you have you own Gauge you can sub in that one.)
The Glow Plug Adaper can be a little fragile.

Ebay sells individual adapters (as well as kits similar to the Harbor Freight kit). However, you will have to contact the Sellers to determine if they can be used with your Gauge and hoses.
