I quite like the high backed seats, my 110 has some in which are considerably older than yours and have a company name on the back for the seat conversion. It doesn’t really help you I know!
I feel your pain... I’ve just come back to the LR scene after I regrettably sold my old 300tdi D1 nearly 3 years ago. I bought a defender 110 (a vehicle I’ve always wanted) last Saturday, got her home fine.
went out in her on Sunday and she spat the dummy out blowing the head gasket at the rear... I’ve done the headgasket on a 300tdi now to tackle the 200tdi
