what kind of speedo do I have to get in order to make my nv3500 work in my c-10

I have heard of some people using some type of adapter, but I started to think, why spend all that money on something I cant appreciate

A nice new gauge in my cluster would be nice. all i have to replace is the Gas gauge and everything would be new!:metal:

any aftermarket electronic (not mechanical) speedometer should work. The slickest I've seen is VDO's, which have an adjustable "pot" on the back, allowing almost infinate tuning.

I saw some of those and I think it would be a lot cooler than getting some kind of adapter
