D2 ABS Sensors

Evening all, just a quick question and I know it's prob a stupid question, so I'm attempting to fix my dad's D2, he has a d2 with 3 amigos up on the dash board stating rear left and rear right corner valve power amplifier open circuit, he also has the exhaust valve power amplifier open circuit and I was wondering what can the cause of this being?

Dad also has a spare D2 for parts which are working fine just the chassis is completely rotten and nobody wants to do any welding to try to help him out or fix it for him.

So I was wondering if there anyone out there in Moray in Scotland that could possibly help him out with that problem?
AND:-
does anyone know if a 2002 range rover abs sensors would fit onto a d2 at all??
Sorry for the questions as I make myself look stupid sometimes but being a chef myself and trying to do ABIT of mechanicing for my dad whose 79 is quite tough to say the least so any help would be grateful or advice as I'm not specialist

Hi. Those fault codes have nothing to do with 3 amigos cos they are about SLS ... was it converted to coils? ... you need a more reliable diagnostic tool to read the fault codes

RR ABS sensor would not work for a D2
