 To tear out the back firewall or not? Please help me decide, I think the rust may require it... |

This is certainly not what I expected down here.  Group: Members Posts: 849 Joined: 21-May 09 From: Bodymore Murderland Member No.: 10,389 Region Association: MidAtlantic Region  |
So I removed the back half of the wiring harness I peered into the area between the firewalls some. What I saw seemed to make me think if I do not cut access holes in the back firewall to fix what is starting, I may be putting a lot more work into this car in the future................

Can't see any pics (IMG:style_emoticons/default/confused24.gif) but if you are talking about the double-walled lower portion of the firewall, it's MUCH easier to access if you simply remove the rear bottom part of the floor pan.
This will give you access to the *complete* double walled section and it's very easy to work in there that way, plus, you can close it all up easily by simply spot welding the floor-pan piece back on. IMHO, much easier than any "access hole" can ever be ... (IMG:style_emoticons/default/popcorn[1].gif) |

Wow. That's nasty. I'd tear it out just to make sure.

I will take another pic and post it after work when I am back home. Do I just sort of cut it where it meets the inner rear firewall that is in the cabin, and then spot it back up on both ends? |

You should be able to drill out the spot welds on either side of the firewall and then cut the floor pan in a way that allows you to spot weld the floor piece back on later instead of having to do a butt-weld. I'm at work and don't have any pics right now ... (IMG:style_emoticons/default/smash.gif) |
