invisik,

Before you remove anything, test the GP for resistance and even better, current. You can do this thru the connector on the GP cable that plugs in to GP relay with out removing anything else. You might not have to remove as much as you think and if all the GP are OK, you wouldn't have to remove anything.

Of course Murphy's Law says that if you have one bad GP, it will be in the worst possible location to R&R.

I see what you mean by the pictures that your GP are nothing to R&R like the ones are on the older 617 type engines. Sometimes older is better.
