Well, there is about 8 gallons of gasoline on my driveway this morning (66 Valiant)

That Canadian tank is the one you want. That is the one I put in my 66 Dart and I have no complaints. If you are keeping it, it is better to bite the bullet and just do it.

Are you still in town or down at the coast? If you are in town, you are welcome to swing by and do it here in the garage if you can slow it down enough to get it here. I am no expert, but have done 2 of them.8)
