Master cyl for 5 lug

I'm thinking of doing a 5 lug swap on my 86. The parts I have are: rear, Ranger/Aerostar axles and Aerostar 10" drums. Front, 2000 Mustang lower arms, spinles, rotors, calipers.
My question is, will I need a different master cyl do to the fact that the calipers are dual piston units? And how about the Aerostar 10" drums out back. Do they use a larger wheel cyl?

The brake cylinders you can research yourself. Just call auto parts store and tell them what you have (9")and ask for part number. Then ask them to check on the 10" and see if its the same parts number. I'm pretty sure they are the same.

Bungy,
A couple of critical things that you need to be aware of.

First, you are more than likely going to have to upgrade your front lower control arms to 1994-2004 SN95 Mustang parts (or 1987-88 Thunderbird) to insure that you achieve appropriate camber.

Second, You really should be using 1994-95 style front spindles. With your crossmember, you will not be able to achieve appropriate tie rod geometry resulting in a bump steer issue. See the following link for an explanation of the problem. Although it discusses the Fox mustang, it applies to our T-Birds as well.

Also, if you are going to go to the trouble for this swap, I highly suggest you swap to a rear disc set up. You can get 1994-98 V6 Mustang parts (same as the GT) for fairly cheap and you will be much happier with the results.

Thanks Mr.T All very good pionts and I am aware of them.
I have the A-arms from the 2000 that I plan on using. The 99-04 spindles are actually better then the 94-95 when used on lowered cars which I also plan on doing. When lowered, the steering arm will be in the perfect location. Also I can go to larger rotors in the future with these spindles.
I've read that MaximumMotorsports link before. They say you can't use them with a stock crossmember, because they are trying to sell their crossmember.
As for the rear. I hope to one day get an 87-88 TC rear and swap that in. But for now the drums will have to do.
I found this info on a Mustang site about MCs and it pretty much answered all my questions. Some really good info here.

Bungy, if you want the quick and simple route you can pull a set of ranger drums. They are 9" and slap right on. Just a matter of swapping axels. I was going to do that before I found that I could finally get some nice 4 lug rims that looked good.

Yup, been there done that. We put the Ranger rotors on our 89 Mustang Chump Car racer. Can't get much simpler then that. I have the 2000 stang parts already from a parted out car so I want to try and use those. I'm thinking of maybe making this into an autocross car, but at the same time not spend a ton of money on it either.

Don't know about the Aerostar 10" drum cylinders, but the 9" and 10" T'bird wheel cylinders are not the same part number.

The 87-88 and 1994-2004 SN95 Mustang control arms are longer than the '86 TC A arms. You don't want either of those with the 86 K-member.

Actually Robert, since he is installing SN95 Spindles, he will need them or he will not be able to get adequate negative camber.

I'm still not on board with him using the '96 up spindles ILO of the '94/'95 style, but we'll see how it works out.

I have a set of 01 mustang spindles/brakes out in the shed for my car next summer. When you get this all put togeather, take some pics, I'd like to see how all of the geometry looks.

The Coolcats website has measurements and comments about the mustang slindles. 94/95 are listed to be used with normal height and 96+ is listed to be used with lowered cars looking for a little wider stance.

Some more good information regarding NOT using '96-'04 spindles (unless you change your crossmember). Mad Mike explains it better than I ever could (see post #25). I just want to make sure that everyone is aware of the potential issues. Lowering your car and using a bumpsteer kit will not resolve the bumpsteer issue if you continue to use a pre-1996 crossmember. Frnakly, I am not sure how easy it would be to use a 1996-2004 crossmember with a 2.3L engine without modifying the mount system.
