Concours Driven is the goal for me. I have to admit that I'm conflicted between the FR380 and the F70-40 wide oval available from Coker. I do have a drivability concern for the non radial tire, not ever having driven on them. It would be a bummer to shell out about $1000 to find out that the handling is lousy. So three things have me leaning towards the FR380: (1) drivability, (2) MCA "driven exception" - no point reduction for "Comparable size radial or belted tire", (4) cost ($350 vs $1000 shipped and installed).
The plusses for the Coker wide oval are (1) the whitewall pin strip is more narrow, and the inner edge further away from the rim, looking more like the originals - see pictures below, (2) technology like the original issue tires.
This is also assuming that I can get the FR380 - again I found them at onlinetires.com but have not confirmed that they have stock on hand.
