You might want to read this thread before you order anything:

I didn't read it all so I don't know how it played out. It's 14 pages long....

Keep in mind this was 2005 so things might have changed since then...

If you are thinking of using Terf Inc, be prepared for a long, long wait. I ordered mine at the end of July, paid with a credit card, and still have not seen anything from him. I have been more than patient with him and call about once a month. Last story was that he had an investor bail on him because of the economy and that he had another investor lined up and that I should know more in a couple of weeks. Hopefully he ain't BS'ing me, cause he seems to have a good product, and I would like to get the speedo working on my '71, as my 4L60E has no mechanical provisions, and I am not 100% sold on the mechanical speedo adapters that I see avaliable for the 4L60E's!!
I will keep you informed if I ever get my adapter.... I would just hold off for a bit and see if he ever comes through before submitting a large order!!!

Well this Terf Inc. joker doesn't even respond to my emails anymore. schwoch1 did you ever get a product from them or a refund?

I am wanting to get an adapter for my 70 as a Christmas gift for myself. Does any one have any experience with the other products out there like the cable X. I would just buy it but it seems to have to many problems for a $300 doller product. Any one have sucsess with it or any other products?

Joker isn't the word for it. I kept calling him every other day and he was promising up to the last day that I called. I had it with him and called my credit card company and got a refund that way. I asked him for a refund and he told me he had no money to refund me. My CC company said that was not my problem and they were refunding my money as I spoke to them.
I ended up adapting an electronic speedometer guts from a '96 S10 pickup to the stock gauges. I can do that because my computer for the LT1 engine has a 4000 pulse per mile output that will run the speedometer perfectly!!!
Terf INC had a good product, but if he cannot produce it, it ain't no good to anyone!~!!

It is using the guts of the S10, but the face and needle of the GMC. I am almost done with the conversion, turning out pretty damn good. I had to modify the odometer hole to accomodate the extra digit on the S10 speedometer and the odometer sits slightly lower on the S10 cluster, so I have to open up the hole a bit. I am also using the oil pressure, temp and voltage gage guts also, it is all in the motor harness, I may as well use it. I never liked the idea of running oil lines in the truck and the ammeter never worked anyways, so replace it with a volt gage. I need to figure out how to repaint the volt gage, but one step at a time, gotta get the speedo done. I will post some pics when it is completed!!!
