Only difference between -6 and -4 is the weight in speedometer. -6 is at .8 and the -4 is .77. Early -4 had 155SR15 and used the 120 speedo. All the 914's with 165SR15 used the 150 speedo. -6 always used the 911 speedo.
911, 914-6 speedo usually cost more. With all the tire combo's available there should be no real difference in accuracy.
IF the above speedo is a 914-6 it will have 911.641.502. 00 or 01
It's 911 641 502 01
