Ok guys. Fed up with 1/4 off needles, wrong temp, and missing lines on LCD where "8" looks like "0".

I took out the cluster to get the part no., extremely easy btw. My car is, of course, one of the first production models and DOES START without the cluster in.

My questions are. 1) Do the part numbers on this cluster and the one I am going to buy have to match? 2) Do I have to program anything or is it plug and play
