I fabricated and welded these on a 105r iirc,back mid ‘80’s,very likeable and endearing well built cars I always felt,had a few friends who had them then,one who turned it to a pick up with beautifully sculpted t&g,following the contours of the body with stupidly wide wheels that spoilt the car...
Re attached these limit switches to the opposite side to prevent being hit by falling tree trunks,also made the angle plates above them for additional protection.
I’ve had good service from Adrian flux ,always used them for 8 foreign trips,and pay £100 for 30 day cover,last year had two incidents reversing in parking spaces,one which damaged my camper,paid pdq.
