Fixing oil leaks on my 305 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Going to start this week on fixing some minor oil leaks on the front of the 305 to get it ready for the 3000 mile round trip to Texas and back in June.
I started today by putting it in the garage where I can work on it for the next few weeks without moving it. I got the air housing off so far. Just going to take my time and do a little at a time. Winter time so not much driving it anyway.

My plan is to take all the belts off and replace with new ones and keep the old ones for spares during the trip. I have oil leaking from the timing gear cover and front of the oil pan and on this model engine you have to take both loose to fix one are the other. So I'm going to replace both with new gaskets and sealer plus paint whatever I can. New cranck seal rear main seal the works. Going to pull water pump and paint it and clean up the front of the motor while at it.
New plugs wires and such also.
Anybody have any tips for me?

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
