Aftermarket version of the rear R/H floorpan for 1992 on cars.
Appears to be a part section of the genuine whole length floor Right hand side.
This has extra length to go just under x memeber at 37.5"95cm long and under glove compartment-one deeper groove for wiring/pipes? and the
MS26R pre 1991 floor has glove box cut outs and only 31.75"(80.5cm) long.It would appear that this is an under panel whereas the early
MS26 is an over/fits inside panel.
