Porsche 911T 1971 LHD (UK)
MRD 727J 1971 2.2 911T Chassis No 9111101045
Originally supplied new in Oakland California USA.
Imported by myself In 2000 & since undergone restoration by myself.
As the car had spent it's life in a warm, salt free environment the
chassis was in A rust & accident free condition, it has been my main
aim to rust proof the car As the early chassis had little preservation
done from new, this was done by a Company called Before & After (Newbury),
I also spent considerable time Ensuring all box sections & cavities
were protected. This is a brief explanation of what I have done to the
car, all costs I have incurred I have receipts for , & as yet, I have
not added it up!
