Interior/seat swap

[84chevyguyid]

I am doing some work on my 84 chevy pickup, swapping out the tired old seat for a 60/40 grey cloth bench seat out of a 97 chevy extended cab and changing the interior color to grey to match the rest of my 80's chevys. The seat went in real nice and I got a silverado for parts that I am getting all the interior pieces out of so I can have a headliner, (mine didnt have one), some of the pieces are already grey but some are red/burgundy and need to be painted. Also swapping out doors so I have power windows/door locks. Swapped out the steering column for a tilt one with an automatic, mine is a standard and I am going with a 700 trans cause 4.10's and no overdrive sucks when every place you drive is a 90 mile round trip, ah the joys of living out in the country. Anyway, people tell me SEM is a good paint to do my interior pieces with but does anybody know what number of paint I need to match my 87 suburban grey with? They give me a can of 15163 and while I havent sprayed any of it yet, it seems a little dark looking at the lid now after I got it home.
