Has anybody heard of a guy named Arthur jackson who was good with Lseries engines?

yes,i've had work done by the fellow himself for the last (takes off shoes & socks to count) 20 years.he is now at smithfield here in sydney,but only on weekends,as he's helping stewart wilkins prepare a 260z for classic rallying at stewarts factory in windsor.his current address is
14/10-16 sturt st smithfield,just off the cumberland hwy,next to peter
warren ford,or call him on 9892-1230.he is one of 2 people in the motor
industry who's advice i believe instantly,i've never had any of his work fail on me,& it's always interesting to see what he's working on whenever i visit.100% recommended.
