I also have a "newer" looking 5" tach in the Opel. Nice tach... works GREAT.... BUT......That's a nice item! I've been thinking about switching my old Sun tach from my Camaro to the Austin, and putting the Autometer tach from the Austin in the Camaro. The Autometer is a very nice tach, but just looks weird in the Austin.
I have the same tach, been some what looking for the old Football 5,000 G tach that uses the transmitter, or the second Gen 8,000 grand tack also uses transmitter. Sinse everybodys going nostalgia they`re hard to come by or they`re to exspensive and not sure if they work. Might have to go with a repop...http://cgi.ebay.com/ebaymotors/SUN-...Accessories&hash=item2a143b8002#ht_500wt_1174I also have a "newer" looking 5" tach in the Opel. Nice tach... works GREAT....

This Winter I plan to re-do the dash with engine turned stainless steel & add old school Sun gauges (blue-line) along with the "right-look" SUN SUPER TACH for this old-time ex-drag car.....
