Thanks for the info. The speedo difference doesn't bother me much. I'd just like to keep the revs down as much as possible when cruising.

I have an early 1971 240Z with a stock suspension and American Racing 14"x7" mesh wheels. I am presently running 195/70R14 Goodyear Eagle tires that have aged out and need replacement. The Goodyears have a slightly smaller diameter than the original tires so the revs are higher than originally intended (inaccurate speedo as well). I'd like to go to a slightly larger tire to "correct" the speedo. A 205/70R14 would fit the bill except that I've heard that with early cars they may rub when making turns. I don't want to do any body mods as I'd like to keep the car stock. Does anyone have experience with the 205s on their '71 cars?

The oil pressure/water temp gauge on my early '71 240Z no longer works. I've replaced sensors and done all the usual tests for meter deflection (shorting against a ground) and it's kaput; I guess the gauge's voltage regulator. I have purchased a used replacement gauge on ebay that the seller listed as "working". Does anyone have a suggestion on how I can check out the replacement gauge before I start tearing the dashboard apart. I'd hate to go through all the aggravation of installing a broken gauge. Thanks

I'm interested in installing an AMCO front bumper override bar. Should the rubber on the bumper uprights be trimmed so that the overide bar sits directly on the metal? With the rubber under the override bar it doesn't seem to sit level. This is for a 1971 240Z with stock bumpers. Thanks.
