Caliper Differences
Anyone know why there are different part numbers for the front calipers between the 71 and 72's?
Master cylinders = same Pads= Same just a thought...... Smitty

Re: Caliper Differences
IIRC, its the banjo fittings on the front hoses that were different.With the different fittings, the calipers were machined different for the brake hose....crazyAL

Re: Caliper Differences
So will a 72 work with a 71 hose?
"Update" The hoses are the same part numbers, so lets try it and see if it works.... Smitty

Re: Caliper Differences
72-73 calipers are the same part numbers......i think it goes all the way up into the 80's for the calipers....

Re: Caliper Differences
i've never understood why the '71 has a different hard line kit than the '72. Shouldn't the hardlines be the same routing? I've never seen 71 or 72 hardlines, I just know they are different part numbers in the catalogs...
