Reply With QuoteI have done a couple of firewall swaps. Off hand, I cant' think of any specific parts you'll need in advance but as you go you may find various clips and plastic plug inserts for self tapping screws which are damaged. Depending on how fussy you are, you may like to replace these.
Suggest you get a box of ziplock sandwich bags and a marker pen and diligently label and categorise all fittings and fasteners in separate bags. Be as methodical as you can, take photos and make particular note of where/how the wiring loom runs and the order in which it comes apart - it can be a bit of a puzzle. There are also various shims for the steering column and firewall support brackets which will need some fiddling to make everything line up.
Consider having the replacement fully sandblasted and primed in an industrial grade epoxy once the welding repairs are done. Another suggestion is to tip the replacement firewall upside down once its painted and get fishoil or lanolin etc to flow downwards into the upper parts of the cavities, before you fit it. I also drill a small hole in each footwell rib cavity and treat with fishoil etc while moving the firewall around to get it flowing everywhere internally.
Its a big job, time consuming and not to be entered into lightly, but very doable if you are systematic about it.
