Technical electric speedometer

hi all.
got a little bit of an issue,
doing an engineswap in my 59 caddy with an ls1 and 4L60-E.
iknow i know, the original 390 is an cool piece, but i did buy my car with out an engine , and got a great deal on a complete ls1 engine with ******.

so heres one of the issues i got now, dont wanna use the ****py looking expensive electric to wire motor stuff, just one more thing that will break,
im thinking of an small electric display or round speedo meter that i can fit in one of the round holes on the dash,

any ideas ?

 

Yes, get this- http://www.shiftworks.com/tailhousing.htm#4L60e

and keep your stock speedometer.

I used this on my Nash so I could use the stock speedo and the ****** would still shift
