parts swap; middle seat bracket [front, 1985 110]

Hi everyone,

I've got a spare rhs middle seat bracket, what I need is a lhs middle seat
bracket. As they're quite pricey, I'd rather see whether there's a chance of
swapping my spare for the one that would make my set. In good condition; I
think the bracket was identical for as long as there was a middle seat,
certainly from 1986 onwards according to the 1986/7-> parts manual. I've got
a spare MTC1714, I'll swap for MTC1715.

Regards

Mark
