Odd question between Buicks of 1947-1949

[Scott Farrington]

I have an odd question (Maybe?!?)

One of my 1947 parts cars, a model 51, has an almost PRISTINE trunk floor.  Even the spare tire well is complete and intact!  Compared to the rest of the car, it looks remarkably salvageable/usable.  So, my question is this:  Are the trunk floors pretty simular across the series or does each one have its own stamping?    Next up:  Will a 1947 Model 51 trunk floor be usable to a person with a 1949 model 76S Sedanette?  Trying to help another enthusiest out here.

Thank you all for your wisdom and expertise!!

Those Buicks were completely redesigned for 1949,

so I don't think there is much commonality.  Others

can surely give more detail.

Buick changed tire size from 1947 to 1948.  The 1947 spare tire well is to narrow to put the 1948 tire size into it.  This is the case for a Roadmaster.  I'm not sure on a Super.

A 49 sedanet don't have a spare tire vell. Spare tire is lying down on the trunk floor( not enogh space to stand up)

Hello as mentioned the 49 Buick was completely resigned from the previous years ,trunk floors were even changed mid year from horizontal mount to upright,also causing a change in the deck lid at least on the convertible,,perhaps a floor from another C body car Cadillac or 98 Oldsmobile could be used but finding one isn’t likely .If the trunk floor is pin holes rust, usually from spare tire and most of metal is still good,you may be able to sandblast both sides and use por 15 and fiberglass mat for a repair.
