If non-factory is OK, then I would recommend looking at the Prestige Series from Auto Meter (a competition-proven American brand), either in Black Diamond or Prestige Pearl. A 5-gauge set in Black Diamond (GPS speedo, WT, OT, fuel, and voltmeter, including all sending units) is $791.99, add the 8000 RPM tach for $266.85, a grand total of $1058.84.

They have a nice period look which doesn't scream "T-Bucket wannabe" the way their original Antique series does.
Auto Meter also offers a Cobra series (downside: reverse-dial tach & speedo) or Old Tyme (just a little too far into Old Tymes for a TR, IMO).
You can order direct from the Auto Meter site, or I happen to work for an Auto Meter dealer -- we'd just have to order them, which would take a little longer than going direct.
