well it's a brillianr classic car!!
congratulations on such a find.
is the car still very original?
if so then don't modify it at all.
if it's already been played with, get a three litre essex or a small block chevy or ford lump and put that in.
drop it about three inches and put on some 15x8.5 revolutions.
i think that would be fookin mint in passion purple with stratos silver accents!
what do you think??
