Hi there Guys

Does anybody know where I can buy a G force sensor for a GC8 (code 56 g force sensor shorted, history code) also anybody with this code
and also a rear wheel speed sensor aftermarket (not much on ebay new)(code 25 open or shorted)
I have had an abs issue for 6 months after I spiked my alternator with code 51 valve relay on most scanners, now my tyres are square and I'm seriously ready to do an insurance job on it...
GGRRRR to my no ABS
