Dave,

The nylog only needs to go on rubber parts, you need not use it on threads and such.

You don't need to torque the connections, just snug them up tight with a back up wrench.

The parallel flow condensor for LESS money is a no brainer. Since you have to replace the condensor anyway, and your building new hoses anyway, you will not only save money but also will have a more efficient system. Although there are other variables, the "capacity" of any air conditioning system is almost always determined by the condensor heat exchanging capability.

I have to pass on your offer to let me share in the fun of tearing apart the dash. I think that would just be more fun than I could stand.

Good luck,
