Ok I did see an artical some where I have done some searching and not got the right info..
OK I have a LWB 1969 912 and I have some 911T brakes..
I want to swap them over as the 69 912 has a one year only rear discs $$$$$$$
and I want to upgrade to better twin vented discs as the motor going back into the car is up from the standard 90bhp to 125bhp to sensible to upgrade the brakes..
So I will need to be 100% sure on the caliper type but I am sure at the time I did this research in order to buy the right claipers
can any one help either with the link to tell me how to do it or give some info for me to get started
thanks alot in advance
