Ugh, that floor pan repair is a bit of a bodge….
Choices - you can cut a replacement out of a wreck; they're pretty much the same from 74 to 93. Or is your want brand new panels, VP Auto stocks replacements, as does Brookhouse (UK), but Wolf (US / Canada) doesn't cover 140s/240.
What are you planning to use to replace the hard, white putty used to hold those floor drain plugs in place? I have number of them which need to go back on the 142.
Oh yeah, btw - those 2 screws which attach the bottom of the centre console to the backing plate (forward of the transmission shift lever)? Don't lose 'em - those screws are unique to that part of the 240, and aren't used anywhere else on the car or on other models. (Unlike many other 240 and Volvo fasteners in general, the same nuts, screws, washers and bolts are often used in multiple places all over the cars and are commonly used in a wide range of models). /trivia
