RE: discs

[ntolerance <ntolerance@xxxxxxxxxxx>]

Couldnt agree with you more Don. Friend of mine has a 67 Coronet that 
runs 12.20's in 100 degree weather and has 10" drums all the way around. 
Driving on the street, youd never know it.

I went with discs on my 65 well.....because they were in the trunk of 
the car. Parts came from a diplomat squad car. Spindles, rotors, 
calipers brackets, porportioning valve and light weight master.

There is alot of heated discussions about using the later car disc brake 
parts. Without going into it all, I will just say that a friend of mine 
did this moons ago on a 65 Satellite. (back in the early 90's) Car 
originally had a straight axle, and he went to the brake parts from an 
84 Fury. I couldnt discern any difference in handling from any other 
from suspension. The car didnt have a sway bar, but then again, it didnt 
have one from the factory.

I dislike the disc conversion kits that use Gm and ford parts. For the 
money, I would rather just run the diplomat parts. There are alot of 
these cars still in junk yards. (same goes for cars like the cordoba, 
magnum, 75 and up charger, 5th avenue, and Grand fury. All these parts 
CAN be put onto an early B body) For the price of the kits out there, I 
can save alot of $$$ and use that $$ for something else on my car.

Just my 2 cents.
