From Moss Motoring 1985
I have found that the tunnel consoles on 72-76 MGs almost always are broken or chewed up, usually around the console lid catch, or around the four holes where the four screws that secure the gear shift boot fit
New consoles are quite expensive. I was able to repair mine by cutting tiny scraps of plastic from a badly damaged console (I talked a salvage yard owner into giving me one that he knew he would never sell) and then slowly melting the material into place using a pencil soldering iron.
The key to success is to go slowly, and don’t breathe the fumes. A rattail file was useful rounding out the holes to match the original shape. A small flat file smoothed the edges of the square area that holds the tunnel lid catch. The fit was perfect
