I would like to know which speedometer should fit a 1927 Roadster dash? The hole is already cut - approx 3 1/2" in diameter. I do not have the speedometer that originally came on the Roadster but the gear on the wire wheel AC Gear

shows "AC Speedometer". The bracket in the second picture was with some other parts and appears to be an AC part as well according to pictures in Russ Furstnow's book. Cover
Can someone post pictures of speedometers that will fit the hole and be year appropriate?
Thanks for the help.

This is the AC setup. The heads usually do not work as they were made of pot metal which cracked

The AC drive at the wheel is on the drivers (US) side. As Will said, the original AC's speedometer head in most cases, the internal pot metal is beyond use. It swells up and cracks rendering them beyond repair. There are other newer AC speedo's that will work but do not have the old look that may or may not have the trip miles. The gear on that wheel looks pretty bad, see how flat the one Will shows is. Even if the dial is on 0 ask and if it does not move, do not buy. If it is not on 0 keep looking.

Many speedo heads will work with the AC drive, but they may not be 100% correct re MPH and distance.

I liked my AC Speedometer, but could not repair it to be original. Here is a picture of the final version. New AC speedometer

I think you would be happy with a Stewart speedometer made for your car. A very good reference is Russ Furstnows speedometer book.

Thanks for the responses.

Larry, I would be happy to use a Stewart speedometer (or other brand) but would prefer it to be age appropriate (Thanks, Mark and David). Since the hole is already cut in the dash, I would like to install something in the existing hole (about 3 1/2" in diameter).

Page 68 of Russ Furstnow's speedometer book shows two likely candidates - The Stewart Model 160 (about 3 1/8" in diameter) and the Model 490 (about 2 1/2" in diameter). My questions are:
1. The mounting brackets for the Model 160 are shown but how do the 3 tabs mount to the speedometer head?
2. How is the Model 490 mounted in a dash and is there a mounting bracket for it that will cover the hole?

Do you have pictures of how these two models are mounted in the dash?

Thanks for the help.

David, your speedometer reminds me of a news article I heard today. In England schools are removing all analog clocks and installing digital ones. The problem is their students can't read analog clock faces! I think the problem is that their government and teachers do not understand the concept of "school"!
