Need some part number help here
 

well, i tore apart my front suspension today to make way for some new stuff. i want to get a lot of this done now so i dont have to take it apart again.

i want to get new calipers, rotors, and brake pads. i called o reilly and they said a 67 (which is what i have) didnt have disc brakes up front, it only shows drums. he said he checked his book and nothing in our year range came up for disc brakes, i was thinking maybe its from another year but i know at some point during 67-72 there was disc brakes lol . so, can someone help me out with a part number for these rotors and calipers?

also, when i pulled off my spindle today, i noticed when it took the rotors off that they have a bearing in the middle. if i bought new rotors, do they come with this bearing?

im just looking for basic replacement parts, no performance or upgrade stuff needed here ;)

thanks for any help!

Discs started in 71. You need to purchase the parts that are the correct match for the spindles you plan to use (71-72 or 73-87 spindles). The rotors use inner & outer bearings. The inner bearing is retained w/a seal which is what you prob are referring to.

Re: Need some part number help here
 

ok. when I bought my spindles I ordered them for a 67, so I guess I need to order a 71-72 rotor. so for the calipers, I would ask for 71-72?

Re: Need some part number help here
 

I would only be guessing as well.

I ordered spindles for my 68.... they were for a 73-87. Are the spindles you bought supposed to be a 'direct swap' allowing you to re-use your tie-rods & BJ's? I purchased 73-87 parts for mine because I confirmed w/the manufacturer that's what they needed.

Regardless, I'm fairly confident the calipers were the same from 71-87 (HD 1.25" version). The rotors might have different p/n's though but as long as you get the correct rotor for the spindle you should be good (1.25 or 1").

Re: Need some part number help here
 

You can order 71-72 calipers,... but the 73-87 (HD 1.25") calipers are cheaper.
What brand of spindles do you have?

Re: Need some part number help here
 

well the part number I found myself is 81-60258 from o reilly for the rotors.

I ordered my spindles from cpp..for a 67.

and the balljoints I already pressed in were 67-70 in my 70 lca's. so the spindle should be right for my lca and uca..

Re: Need some part number help here
 

so will the 73 -87 calipers fit on a 72 drop spindle

Re: Need some part number help here
 

yes.
I have a set on my '69.

Re: Need some part number help here
 

sooo...

what your saying i can get is..

71 rotors, 73+ calipers, on my 67 spindle and balljoints?

let me make a quick list of part numbers so i can be a 100% right when i go get my stuff!

Re: Need some part number help here
 

I created a spreadsheet for front end rebuild awhile back, here it is if it helps. I do need to add Caliper part number though.

Re: Need some part number help here
 

71 rotors, pn 81-60258 - 29.99 each

73+ calipers, pn 18-4035 (R), 18-4036 (L) - 11.99 each

67 upper balljoint, pn K6024 - 14.99 each

67 lower balljoint, pn K6023 - 14.99 each (already installed)

and these are all house brand...

does this look about right?

Re: Need some part number help here
 

man, i need to install a key for microsoft office, i cant look at it lol

Re: Need some part number help here
 

You can even use the 73-87 HD rotors if you want. They are cheaper also.
Just make sure to get 1.25" rotors and calipers for 1.25" wide rotors.
I just tell the parts guy that I'm working on a '73 truck. Makes it easier for everyone.

Re: Need some part number help here
 

Whatever you do, don't tell them you have spindles for a 67.....

Re: Need some part number help here
 

haha...you guys couldnt be more right! i went through that when i was getting balljoints.

i didnt know 67-72 and 73+ suspension was that interchangeable.

well, i guess ill be getting 73+ rotors and calipers. thanks for the help fellas

*edit*

which brake hose (that runs to the caliper) do i get?
the 67 and the 73 hoses look totally different, and the 67 one is half the price. 10.99 compared to 19.99

Re: Need some part number help here
 

You need either 71-72 hoses or 73-87 (cheaper, but longer) hoses.
The longer 73+ hoses work good with bagged trucks.

Re: Need some part number help here
 

hmm, will the 73+ hose fit my 67 truck? the ends of the hoses look different than the 67. im pretty sure they will fit the caliper since it will be a 73+ also...

maybe im lookin at the wrong part on oreillyauto.com

Re: Need some part number help here
 

I used post-73 rubber lines w/post-73 hard lines on my 68 & plan to do the same w/my 64. The 73 rubber lines should also work well w/the pre-73 hard line set-up as lolife mentioned because they're slightly longer.

Re: Need some part number help here
 

For anyone who does not have Excel, I uploaded the current version of the spreadsheet to Google Docs here - http://spreadsheets.google.com/ccc?k...FNk9IeXc&hl=en

I will keep adding info as I get it.

Re: Need some part number help here
 

Sort of. The 73-87 hoses would work with 71-72 hard lines, but not 63-70 hard lines. If you will remember, 63-70 trucks used hard lines that run off the back side of the crossmember. There would be way too much hose length.

Now, 71-72 ran the hard lines across the front of the crossmember to tabs near the edge. The 73-87 hoses would likely be close enough in length to work. But, if running 71-72 hard lines, I like to buy 71-72 dually 1 ton front hoses. I get them from Kennys Trucks. The dually hoses are the exact same as 1/2 ton hoses but longer in length by an inch or so. That gives needed slack when the truck is lowered.

By far, the easiest way is to rob 73-87 hard lines front to back and use 73-87 hoses. The holes were even in the frame of my 63 truck for them. All I had to do was lay the 80 model lines in place and bolt them down. No mods needed at all. Then I run an 80 model master cylinder too so there was no fabrication or modification of the hard lines needed. I used all three replacement 73-87 brake hoses, even the back one worked perfect.

Re: Need some part number help here
 

I've done multiple trucks this way. My current 'Dropmembered' 64 will use them as well.

Re: Need some part number help here
 

hey, i think i will just go 73+ for everything. with that being said about the hard lines, does the 73+ suburban bolt right up to my 67?

i know you said it does for the trucks, but i forgot to mention mine is a suburban

Re: Need some part number help here
 

There's no difference in the firewalls or front rails (burbs vs. trucks) so I wouldn't think there will be any issues.

Re: Need some part number help here
 

what about the brake lines to the rear? or is this something totally different? i just assumed you guys were talking 73+ hard lines all the way to the back.

so its 73+ up front, then original hard lines to the rear?
