What your dad can do is install a Tracker device that you get in SA over the border . Every time you exceed the speed limit in a particular speed zone it will send him a text message . It will also tell him how many ( of how much of a G ) you pulled in cornering or braking .
I used to have this system on all our mobile cranes to monitor safety but that's because these cranes weighed 65tons and you could not drive them longer than 30 mins without tyres heating up . You don't fall in this category .
Maybe ask him to install a roll cage and then you can actually turn it into a trackday car and provided the cage is padded near your head you are marginally safer
For you spares contact AK classics in stijdom park . Talk to kevin strapp . Unfortunately if he does not have stock it takes four to six weeks . ( it goes by ship , then train then gets lost or stolen even possible strike in postal service but most time it take two months ) His details are on google but unfortunately he is at the mercy of the postal service .
Maybe if you pay extra he will get it flown in .
