you are going to need angled boots for PS opti so just buy the correct wire set and don't f around with making the ones you have work. Magnacore 8.5 are like $115 from Lingenfelter
NGK-TR55 plugs or just put in the AC Delco Platniums if you want a 100k mi plug
take a plug socket and modify it like the pic. cut the one side out and take some off the part the ratchet goes into
I have just pulled the stock brackets that hold the plug wires off from underneath and asembled the new wires in them on the bench and re-installed. also on PS go through the wheel well to access the wire loom clips you need to with a screw driver.
'you don't want to do this job again so do it right
