I did finally get my JME gauges for my '68. I was not overly impressed with the workmanship. Looks like JME did some major cutting to get the tach to fit then put it back together with what looks like liquid steel. This caused the right side to bow out a bit resulting in some fitment problems. I had them in and out about 10 times before I could get it to look right. I ended up moving 2 of the mounting holes in my dash. I also had a problem with the fuel gauge not working, but after cleaning the connections all is fine.
Overall, I would say that they do look good and it is nice to have accurate readings. I thought that I had an overheating problem, but the new temp gauge shows 180 solid as a rock. The big tach is nice too. Easy to see and goes all the way to 10k.
