Spark Plug type 82 SC?

[LFogelson]

The decklid of my 82 SC lists WR7DP or DC plugs with .7 + .1mm gap.
But the car has WR5DC plugs in it. I have looked at the archives and seen where other people say it says WR5 on their decklids. Further, the Pelican parts catalog lists the WR5 as the plug for '80-83 cars. Do different cars need different temperature plugs? What should I use?

I use WR5DC in my 81'SC. This is what is called out.

On page 030-8 of the Bentley manual it lists WR7. I have been told this was an error and the correct plug if WR5. I installed WR5 about a year ago, runs fine.

Thanks for the replies. I figured it out. The decklid is not original. PO changed it to a lid from an 1989 - hence the WR7. I can tell by the vacuum diagram...nothing like an 82 SC.
