Hi , Newbie question regarding modifications and tyres.  1967 mk1 mini 1275 ( 1380 in build), reciently purchased and interested in prepping for novice rally type events.  Its currently got a fiberglas flip front , i have read that this will exclude it from Historic class ( eventually to be put back to standard in order to qualify) so what calls if any can we run her in?  2nd question is what tyres as searching the lists in the Blue Book and searching the web  has failed to produce many options . Thanks in advance.
