Thanks guys, i talked to the 2nd owner of my 68 copo (non converted to yenko) car (original owner passed away) but the two were very good friends. He indicated, when they picked up the copo car from the yenko dealer , the car had a SW tach installed (assuming ready for the conversion). He still has the original tach and will be willing to sell it to me...i wanted to do a little of checking around check on the correct type and style...before i send money...
Thanks alot for the info.....
