Hi Wallsy, great tip. Looked there will no luck. I purchased small dentists mirror to help look around. Still no luck. I'm sure when I start the truck the bolt will just fall out from its hiding hole.

Express postage means 5 days from Oregon, so I'm expecting the part on Monday.

The fittng at the front of the engine was really tricky. I ended up using a seal-pick to hold the thing at the correct angle and then could only get one finger to rotate it. Once the threads were engaged I could use an 8 mm open ender for just 1/12 of a rotation, then flip the spanner over and continue until tight.
Hopefully the part will arrive tomorrow and I can complete.

So, the truck has been off the road for the week so I took the opportunity to wash the Pete's Cover - secretly used the washing machine. The problem was I turned on the wrong tap on behind the machine and flooded the electrics, now my next job is fixing the washing machine - $175 for a new motor controller to replace the water damaged one. Double Klutz!!
