14's for the small bolt pattern? '65 Valiant

For a stock looking daily driver I'd go 14" small pattern. The ordinary 14x4,5" wheels are not difficult to find, as mentioned earlier in the thread there are a lot of cars being upgraded to bbp and wheels becoming available. On my '65 wagon I use sbp 14x5,5" wheels. They are a little harder to come by as they were mostly installed on the high performance cars like Formula S, GTS, Duster 340's and so on. But they do show up from time to time and there is a set of 5 for sale in the Tire/wheel section right now.
The extra inch on the 5,5 wheels is all to the outside so they pull the wheel more out from under the car. I love the way they give a stock appearance but is a big upgrade from the small and skinny 13" stockers.
The wagon rolls on 195/75-14 tires. They are a good bit taller than stock which helps on highway rpms, fuel economy, comfort and looks.
This dimension is readily avalable, for instance the Cooper Trendsetter SE, a sensibly priced but very nice tire.

I'll include some shots of my wagon so you can see how the wheels look from different angles. I know they should be bodycolor and they will be soon :)
