So I am just putting off the inevitable.

The old engine in my case will probably just get stuffed in the corner along with the trans, for the future.

Any way I was playing around with my gauges and thought I would pass on my idea for my future Digital speedo. After reading LS171nova write up I decided to try my own for a digital conversion. The stock S-10 digital speedo lines up really well with the stock Squarebody Speedo (as seen in the photo below the S-10 gauge is behind the face of the Squarebody speedo-even to mounting holes line up!). Both speedo's are 0-100mph. The only area that really needs work is in the odometer cut out. I don't know why but Dakota Digital gauges just don't look right to me.

I am just starting to research all of this myself.

Hey Factory Guy! I was hoping you'd chime in over here. Yeah I finally bit the bullet and am plugging away at the swap.

Fuel system: I assume you've read through that separate thread I created on the subject... I will admit I've been struck with Paralysis by Analysis on the fuel issue. I've read that dual tank thread by Hatzie front to back... I'm familiar with the Pollack EFI rated 6 port switch valve, I guess I am just not 100% comfortable with that setup. I know the valve is "rated" for 65 psi, its more the thought of 6 fuel lines, held in place by hose clamps, up under the truck just leaves me uneasy. Compared to a set of nice stout An-6 fittings leading directly to the fuel rail. I just can't shake the feeling that something in that valve, or the switch and its wiring will eventually fail.

On to the gauges... I too feel that the Dakota's are a little out of place in our style of trucks. The newest offering they make looks pretty darn close to original, but at $1500 its a heavy cost. The s10 gauge conversion looks awesome... but i'll be honest its out of my "arts and crafts" ability.

The other link you posted had my head absolutely spinning until the very last post. I'm far more inclined to go with the dakota digital to mechanical converter. It's not cheap, but at a 3rd of the cost of a full set of Dakotas, plus you can keep the original look, and an hour install tops... that's probably my go-to. I've already purchased the temp and oil pressure sender conversion pieces, I'm fairly comitted to keeping the stock gauges (unless a set of Dakota's happen to be under my xmas tree one year lol)

Anways, glad to have you checking in here... I'll be posting as often as I make progress.
