What is the best donor for a rear drum to disc conversion on my '89 Buick Estate wagon?
Seems to me this ought to be a bolt on deal, is it?

4 wheel disc on a tow rig is money in the bank...

Thanks, Paul

Why not run the 91C or Impala SS set up?

Uses LMGTFY. Makes a useless search. Trolling done wrong.

the rear being shorter than the 9c1 is not the problem. the problem is the wagon s axle bearings are bigger than the 9c1. the bolt pattern on the backing plates is different. u should look up tim bigblackbeasst he just did this. you could also swap the whole rear and put in the 9c1 rear. it will be shorter remember. there are post on doing tis also

Well, to the five of you who responded, to my obviously ill conceived question, thanks for the relevant input. Obviously, the proper solution is to cut down a Ford 9 inch housing, order new axles drilled with required bolt pattern, fit the big housing ends and brackets and redrill the discs. I guess I don't want rear D/B that bad.

I guess those of us who are not master mechanics or web masters will have to refrain from bothering the all knowing, I know I will.

I'm off to take some troll lessons, so I can do this correctly.

Well if its the obvious solution,.. why ask,..? and hardly a bolt ftom a donor,.

When i did my rear disc conversion on my T56 wagon,i redrilled 9c1 backing plates,. and used the factory parking brake shoe,.
but its only in 7/8ths of the way,.

I also used C5 rotors,.and calipers,.

But seeing as i like to fab stuff up,.. it worked for me,..

The next one i do will not have a parking brake,. i will use C5 rotors, and C3 calipers,. i built one like that for a friend and it works very well,.

I don't like the spongy pedal with the C5 caliper,..

I think bill harper sells a wagon rear disc kit,. with a split spacer to make things work,.
As was mentioned see big black beasst's recent conversion,.

With any question I have, I first do research. In this golden age of the internet, an answer is a google search away. Being as people have been modding these cars since they rolled off the lot, most of the mods have been done and documented over and over again.

There may not be alot of info out there on boxies, but keep in mind the frame and suspension is the same from 77-96, save for some changes on 94-96 cars to accommodate the lt1, mostly a notch for the AC compressor. Besides that its all the same.

Redcaddy,I dont believe any "tone"was implied to any of the answers you received. Ask a Q. get an A. You will find most on here ready to help a fellow out.

I've only been on this board a little over a year, 99% of the reply's I've received have been on point, helpful and courteous. (some suffer fools more kindly than others)

I took one of the reply's above as a cheap shot. I answered it with a PM to the poster, Not to the board in general. My next post was, decidedly, out of bounds. (obvious solution...) for that I must apologize.

I'm a millwright, not a computer whiz, I'm sure there are 10 YO's out there with better computer skills than mine. I did not use a Google search, I searched on this board, and several other relatedboards, for year/model specific guidance.

My thanks for the help received is genuine, it was on point and specific. Now that the little tiff is over, I'll crawl back under my rock and keep banging on my longroof.

Thanks, Paul

Being a millwright sounds like you can fab up what you need and if you have a lift in your shop all the better.

I sit at my desk banging at a computer two weeks a month and travel two weeks the computer time doesn't feel like real work..... pushing ideas around reports and email no real action wonder how anything was accomplished before them...ha. Jeff

Yes, 35+ years in the trades allows me able to build pretty much whatever I need, but, my old school engineering training makes me loath to re invent the wheel at every turn. I tend to use "off the shelf" components and standard hardware whenever possible, saving the High zoot, one of a kind, unobtainium stuff for problems and situations that can't be done any other way.

As I said in my first post, I thought this would be a relatively easy, bolt on, upgrade. Obviously I was wrong. I was surprised when a search of the Hollander's interchange manual didn't turn up any likely suspects.

I'm beginning to think that Eric may very well be right, if it ain't broke, don't fix it. Electric brakes, on a 2100 Lb trailer, behind a 4100 Lb tow rig= No problem. (I often use overkill as the minimum standard)

Thanks, Paul.

BTW: about the LMGTFY, I heard it here first.
