temp sensor issues?

[schurg]

hello everyone!

I've been browsing the backlog of threads here, trying to figure out what I thought would be a simple problem. I have a 68 c10 with the original dash gauges, but I have a new(er) crate 350cid. my problem is that I dont know what I should do about a temp sender. I didnt think there would be an issue till I found a few threads here talkin about having to machine new senders to fit old motors, or, determining if the resistance is correct for the factory gauge. seems like alot of potential variables for such a simple system. so, my question is; can I go to napa and buy a sensor(that they have listed for a 68 truck) and throw it in there and roll? or will my gauge be all out of whack? I would like to keep all the whack intact :P

thanks
