Spark Plugs Near Firewall with 1" setback mounts.

[Big-Sexy907]

Just wondering, how are you guys changing plugs on the rear two cylinders? My plugs are darn close to the back firewall, and the schoenfeld headers aren't helping for access.

How do you guys do it?

Not sure why you're having an issue... On my '92 with 1" setback I have plenty of clearance between the firewall and the rear plugs... In fact, the rear plugs are easier to access than they were with my 350. Is the firewall different on the earlier GMT 400s?

I haven't had to change the plugs yet as I'm still in progress of swapping over, but I just noticed that they are within close proximity to the firewall. Perhaps I'm thinking about it too much... I'll see how it looks when I get in there.
