Speedo Switch

[zetasig]

Well next question on the list. I have a 1975 2F engine with stock 4 speed and 4 speed transfer,

The instrument cluster I have is a 1970 model. I know the speedo cables are different.

Would it be the easiest to find a 75 era speedo cluster and swap that in? I would like to know how fast, or slow I am going.

Any other hints would be great.

Thanks again.

I would be lost with out all of you.

Check both ends of the speedo in the transfer case and cluster make sure it's not your cable

I have looked before, a while ago, My thoughts are though since CCOT sells different speedo cables for both a 1970 era and a 1975 era. that I will need to match up the cluster to the transfer and buy the later 1975 era cable. just wanted to see if anyone else who has swapped in a 2F has been through this.

The difference is at the speedo. My 71 (and your 70) the cable screws into the back of the speedo. I installed a 78 speedo (it presses in and clips) and only had to change the cable. Also had to rewire the cluster to get the gauges to work.

thats what I figured, so what year ranges will work for the press and clip clusters?

Probably 75 through 79 or so.

I also think the change is at the speedo, so a 71 cable should work for you!

Okay now Im confused, I get the 71 speedo cable right, plug that into the cluster no problem due to closeness of years. Then plug the other end of the 71ish speedo cable into the '75 t case right? So the connections from the T case which are screw ins never changed across t cases right.

This page from SOR says the speedo drive sleeve in the transfer case stayed the same from 1963-11/78! So you should be good with the long cable that fits those earlier years.

Yeah, the transfer case end didn't change all the way up thru 87; it's all at the speedo head.
