98 tune up ?

Going to be changing out plugs on friends 98 Park Ave, 3800 120k...is there any special procedures on getting to the back plugs? I have not seen this or others yet and wondering if they are of the GMs that tilt forward or not. I am familiar with chevy luminas and Impalas any thoughts appreciated.

You have plenty of room in the PA to change the rear plugs. Some people remove the strut tower brace to make it easier. Other than that, it is pretty straightforward.:grinyes:
