Should be exactly the same as this tag on the back of the last 396 (Aug 2nd 1965). Cluster ink-dated July 26 1965.

The only difference in the gauges would be the scale and color zones on the temp, and the endpoint (240 w/no color for '65, vs. 250 with color zones, for '66).

Re: 66 L72 instrument cluster info

the reason I ask the broad cast code is LD with the speedo and /tach #'s not the same on my car as your photo

I notice Long Island Corette lists many dash cluster stickers; unfortunately, they don't give the letter codes for the various speedo and tach combos.

Can you tell us what these two latter part #s are on your LD sticker ? Maybe we can work backwards to what engine and option(s) this applies to.

This issue came up a few months ago. Do an inquiry on the subject and I believe you'll find a fairly complete list of the numbers for the various combinations

Re: 66 L72 instrument cluster info

The limited information I have indicates that LD would have a tach redline of 6000 rpm.

6455367 is the standard '65-7 speedo w/o '67 speed warning (U15).
6412222 is the 5300 RPM redline (base engine in '66-7).

6412522 is the 6000 redline ('65-7).

From P&A30B Corvette catalogs, Gr 9.750 and 9.761.
