Ray, Thanks for your input.I have located a NOS 6cyl. 12v Sun transmitter But I thing I'll wait until my new used cluster shows up to see what i have. there is no marking on the cluster indicating 6 or 8 cyl. The man i bought the cluster from said he pulled it from a larger truck years ago and cant remember what engine it had. whats odd is the cluster is the older style before 63 ive attached a picture my truck is a 61 K10 with the 235 6 and idiot lights so im wanting to install the cluster with guages and a tach. Ive read that I can buy a tach adapter the will correct the signal if its a different engine than what i have.
