I've got a T bucket I built back in 68, it's now 40 years old and been through 3 engines and 3 or 4 transmissions. I decided to rewire it this winter, I removed the dash and entire interior and got to looking at it. The original floor (3/4" plywood) that I glassed in way too many years ago is full of holes from the various changes I've made to it and it's getting springy (it gives a bit when you step on it, more from the lack of wood between holes then anything else. Today while trying to straighten out my non heated garage in preperation for the on coming winter I came across two sheets of 2'x4' 16 ga. steel. I'm thinking that I could cut the access holes I need for my master cylinder, battery etc in the steel plate and use the plate to reinforce the existing plywood floor. Do you think bolting the plate to the original wood floor would be enough. I thought about glassing it in but soon realized that the original floor had absorbed enough oil to preserve it for the next century.
