First of all...this is not for the faint of heart...please reference 72GTVA's excellent instrument panel article for differences between different cluster packages and possible modifications which may be necessary. That said... my cars original package was suffering from severe dry rot but still functioning. Anyone with these cars understands how difficult night vision on these gauges is... ...terrible is being generous. Plus I wanted something a little different. I pretty much am of the opinion that the only proper way to upgrade instruments on our 'cheros is to make a new panel with quality instruments..as several on this site have done. That being said...i'm too poor/ not technically skilled enough/ challenged on time... so this is what i did. http://stores.ebay.com/White-Gauges/Ford-/_i.html?_nkw=ranchero&_fsub=2&_sid=10585820 this company has recently begun making an overlay for our GT gauge cluster...they also have one for the standard gauge package. This applies to the 72-76 overlay specifically....they also have early models as well as 77-79 This is the package $20...seems a good deal.. the overlays are basically a 3m decal type product... I had used one on a 81 mustang years passed and it did well.. The recommended installation package... (consisting of a squirt bottle/squeegee/razorblade for 5$ additional) is unnecessary..but i decided to get it anyway.
