Just google Newport Engineering
I have their units in three cars and all work very well.
When doing the change, I strongly suggest removing the front seat. Makes lot of room to work.

I used Newport. 5 Years with no problems. Get the Knob conversion so You can use your original Knob. I wouldn't bother with their "intermittent" kit.
The only problem I had was working under the Dash I got disoriented as to up and down and installed Bracket upside down first time. Otherwise the Conversion is straight forward. Use an Inline Fuse for Power.
