This was missing when I found the car (1974 4/4) and I'm assuming that some marine ply-wood with epoxy will suffice - assuming I can get the right thickness.
I noted some older posts out there where people seemed to be creating additional shelves between the battery location and the parcel shelf and I was wondering if anyone has completed a project like this for a 4/4 and has photos and feedback to share on what they did ?
Thanks
Dai, a74 car probably didn't have an undertray as a standard fitting. They had a sort of toolbox under the bonnet (hood).
