| Subject: | Re: firewall problem |
Rowland,
Like Bob, large holes to accommodate ...... etc.,
but made s. s. doghouses with a slot just for the cable ahead of rubbing
blocks.
Port one permanently attached to the foot well.
Attached to main firewall with smallest anchor nuts and NAS bolts.
Starboard one to side piece, port one to both bottom piece and top piece.
I have lowered foot plate (Ian Rickard 10665), so my details may not be
valid.
Ron Parigoris did this (see europaowners site) and I couldnt help myself.
Not tested except for free movement.
