80mm caliper

[bartz paul]

Frank:

Thanks for the clarification. Now I understand.

GM numbers I gave are different than your numbers, if you check, and I
realize you say casting numbers. Last four of the numbers are 5385 for =
the
left side and 5386 for the right side. Don't know what relationship =
casting
numbers are to part numbers???

NAPA numbers I have are 242-2072 for left and 242-2073 for right sides.

As far as Bobby is concerned, I recommend you contact him and find out =
if he
feels up to helping you. Or maybe you would care to go to his place =
and do
the work??

Paul.

Lets start over again. The only reason that I mentioned the drum brakes =
is.
The Gm =BE and one ton truck with 13" rear drum bakes have the 80mm =
caliper up
front and also the larger master cylinder.

Checked the casting #. They are 18003532 GM L and 18003533 GM R. Your =
Gm #
have a 1 digit instead of the two 00. Paul I believe that they are the
correct parts but I will check them again. Will cross reference the Gm =
# at
Napa and then ask what year they are for. Maybe you can e-mail Napa =
part #.
I could then do it over the phone.

Paul I understand you are a good friend of Bob. Do you think that I =
should
just go ahead and have the work done locally

Frank:

I'm picking up one caliper, using your Autozone numbers, from our local
Autozone store on my way home from work.

I'll compare it to what I have on the coach this weekend and let you know.
It may be Monday before I get back to you.

Returned from doing my follow up. Napa # are for 79-95 Chev and GMC but
not all applications. Auto Zone 79-87 C-10 C-20 With 13"x2 1/2" rear shoes
will give you the 80mm front caliper at $12.99.

Frank:

Picked up the 80 mm caliper and a hose from Auto Zone.

Yesterday, I took off the right front wheel on the coach and removed =
the
caliper mounting pins, pulled the caliper back out of the way and =
mounted
the new caliper in place. It works. The hose was the right one also, =
with
the proper end on it to mount to the caliper. Incidentally, I believe =
if
you look closely, the first 3 in the casting number you listed is =
really an
8. Look again and you can see that the 3's have a flat top to them =
whereas
the 8 has a rounded top.

I'm going to call Leigh Harrison and talk to him about the caliper and =
hose.
The NAPA hose (part number from Leigh) I picked up over a year ago as a
spare, did not have the proper end on it and would not work on the =
caliper.

Paul... Glad that you took the time to try the fit. You had me 2nd guessing
myself. Do we now have a new source for 80mm calipers at a rock bottom
price...................Frank
