Tach install questions?
I'm woundering which way is the easiest to installing the tach? Is it to lift the dashboard or could you get access from under, right by the steering column?
Thanks/ Emil

You don't have to take out the dash, but you do have to remove the clock/clock delete and install the tach from behind. I would suggest that before you start this, you get an Oldsmobile Chassis Service Manual (available as a book or a CD on eBay) and/or an Assembly Manual (go here:http://wildaboutcarsonline.com/cgi-b...aldisplayed=21 ).
Also, you will want to remove the front seat(s) and console (If you have one) before you begin. It seems like a lot of prep work, but you'll just end up taking them out anyway unless you are the size of a 5 year old, so save yourself the time and aggravation and take them out, then you can lay on your back to work. You will also want a good flashlight and glasses to keep things out of your eyes.

You have to crawl under the dash. There's no way around it. In my younger days I would hang upside down with my legs draped over the seatback and my head on the floor. These days it's easier to pull the seat out first.

I did it on my '68 about 6 weeks ago and I'll have to do it again here in about a week. Somehow, at 60 I can still contort myself into position with the bench seat in place. It's not very comfortable, though, and there's a lot of swear words before the job gets done!

I wish you the best
I changed speedo to floor shift on my 69, looked like i had been in a fight, forehead scratched from heater vent, arm scratched like it was in a bear trap. now for some advise, I went to local hardware shop and bought a cheap bit set with a little p.o.s ratching bit holder and it helped but still a pain. the 2 srews on each side that hold the can were the worst. you will need to get a light that you dont have to hold.

It makes it a lot easier. Did you take your seat out? Once you do that you can really lay down on your back and get your head up under the dash an see what is what under there. Definitely need the flashlight as well. 1/4 drive sockets with 3 in and 6 in extender bars is what I use to get to the screws.
