    488461E1-E4C3-43E1-8C97-42C7E256E96A.jpeg Working on preparing the A for the channeled floor removal. Original rails are shot.
    Can anyone advise how and where these rails are attached to the sheetmetal on the body? I have found a few rivets at the braces but on my body can’t see any spot welded locations.
    Due to the state of my hacked floor I am flying blind on the reassembly method other than a few pics I’ve found of others projects.
    Any help is appreciated!

    Been a few years since I did a A , if i remember correct ,cowl panel has a 90ish lip & is spot weld along bottom to sub , ( like cowl to door jam A pillar) & there should be another brace from sub rail to firewall, & if you do not have that brace /support its not reproduced,

    Thank you! Are the lower cowl and 1/4 panel bottoms spot welded to the subrail? Only welded spots I can find are the door opening brackets welded to the rail. Outer Sheetmetal skins are not attached on my car. Not sure if this is correct?

    Headed to Pro Stick race, If no one Else chime In before I'm back, I will take a look & pics , Im sure its tacked across bottom,
    Or maybe crimped , its been 10 years since I did compleat sub rail , On my 32's I know its spot weld along bottom

    I always thought the outer skin was just folded around. Maybe a tack weld at the corners, but mostly just folded under, and up. Making a perfect trough to hold water and debris and rust out.

    Same thing on 26-27 T bodies.

    looks like your subfloor extensions have been narrowed,
    they are $300 a pair new... i have some used if the shipping isnt a deal killer...
    mine still have the toe boards attached... pm me...
