Is there is a good way to do that? I purchased new wiring harnesses from Clark's, including a new fuse box, all of which are for the manual transmission '68 car. I figure that that part won't be an issue.

A replacement quartz electronic clock mechanism would make more sense in classic automobiles, if the external face and hands could be retained and the internal replacement electronic clock could be hidden from view. I believe that the original electromechanical clocks will unfortunately fail repeatedly due to burned contacts that suffer some damage each time the contacts close to rewind the mechanical clock. Vehicle vibration and environmental shock to the mechanism probably doesn't help with mechanical clock longevity either.
If you want to retain this instrument in the Corsa instrument cluster, you may want to look at the replacement electronic clock mechanism shown below. These have been offered on eBay for years...

The manifold pressure/vacuum gauge was a part of all Corsa instrument panels, but they were primarily useful only in the 180 hp turbocharged Corvair Corsas. They are not of much value in a normally-aspirated Corvair engine. If you wish to connect this gauge, you will need a tubing kit like the one listed below. On the 140 hp normally-aspirated engine, the gauge was connected to a special vacuum balance tube that included the correct fitting. You would need to fabricate an intake manifold connection for this gauge.
Stewart Warner Performance Nylon Tubing Kits M-82553-F
These Stewart Warner Performance nylon tubing kits allow you to connect your mechanical pressure gauges to your engine. They feature high-quality nylon tubing and include a brass reducer bushing adapter and fittings. The Stewart Warner Performance nylon tubing kits have you covered with your choice of 6 ft. or 16 ft. nylon tubing.
The Corsa speedometer is often functional, while the odometer and trip-mileage portion fails due to worn-out drive gears. These components are usually not available to replace worn-out items. The CORSA article attached below will provide some information on Corsa speedometer maintenance and repair. The complete CORSA magazine issue is also attached at the end of this post...
You might also consider mounting modern gauges in the Corsa plastic instrument panel. Seth Emerson offers a mounting kit that lets you mount aftermarket gauges into the Corsa panel. You could substitute more-useful and informative gauges, such as an oil pressure gauge or a voltmeter, in place of the less-useful vacuum gauge and clock...

Kit includes 4 separate plates, Speedo/Tach/Upper center gauge pair/Lower center gauge pair. Fits – 1965-66 Corsa Dash
(The Corsa Dash will fit into 65-69 cars)
Parts are usable individually or in any combination. Upper pair and lower pair are replaced as a pair of gauges. Plates retain the gauges from behind, pressing them up against the back side of the dash. No cutting or modifications to the dash panel are needed. Use original mounting screws. Stock Speedo can be retained. Standard 3 3/8” Speedo/Tach and 2 1/16” aftermarket gauges work fine. Cost $44 + $8.50 shipping
Add $3.96 sales tax, if shipping to an address in California.
Some custom wiring will be needed to install the Corsa instrument panel, either with standard instruments or with aftermarket gauges. The diagrams below will help you to review the differences in the Monza and Corsa instrument harness. The warning lights, illumination lights, turn signal lights, and high beam indicator are somewhat common to both instrument panels.

The Corsa and Monza instrument panels can also develop problems with the electric instruments. The panels are plastic, so a metal conductive grounding strap links the electric gauges together and then ties them to chassis ground at a single point. If the single screw that attaches that grounding strap to the metal dashboard becomes loose or corroded, the electrical ground to the instrument panel components may be lost and this can disrupt the operation of the electric gauges and illumination lights.
