I have a 67 Coupe, 6 cyl, and 3 speed tranny. Eventually i would like to convert it to a V-8 but for now i would just like to convert the 4-lug to 5 lug all around. Is there any issues with doing this and what all would i need to be able to do this?

www.discbrakeswap.com for the brakes, $525 and you get everything for conversion to 5 lug up front and disc brakes. For the rear, look for an 8" on craigslist or eBay or locally for $150-$200. It costs about $170-$190 to redo the rear brakes (keeping drum) with everything new including wheel cylinders and drums from AutoZone.

That should be just about it, ~$1,000 and you're done. Then when you get ready to do the swap, get the suspension parts from any of the Mustang parts places.

And you'll have to shorten the driveshaft, and depending on what rear end it is, you might have more fabrication, with spring mount plates and stuff.

I've got the driveshaft from a '65 289 car and a '66 I6 car and they are exactly the same, no shortening involved.

I am not sure how to go about changing to five lugs without exchanging parts. The route I took was a complete rebuild of the suspension starting at the steering components themselves. I assume that the the spindles would need to be changed like on my 66 to upgraded V-8 spindles since you are wanting a V8 later on anyway there is no reason to do everything twice. The spindles are an easy purchase off ebay for a good price. Now in changing to five lug in the front I ordered a disk brake kit from summit that solved the switch from 4 to 5 lugs. The kit was WIL-140-4304B. I say use disk because you are gonna want the stopping power when youget an 8 IMO. I am not entirely sure how the kit works with a linkage system because I replaced mine with a R&P from flaming river.

The rear of the car had a tiny rearend so I ended up purchasing a ford 9" that was already 5 lug so the rear was just a big purchase.

It was definitely an expensive process but, if I did it again I would do it the same way.

I am swapping my 65 to disc brakes in front in about a week. I will sell you all the parts off my car if you are interested. New front brake lines, new pads, and one new wheel cylinder.

Hi!

Just to ask for our 2nd Mustang: Is there a posibility to change 4 to 5 lug without change the axle istself? Maybe other Axle-Shafts?

musting

I have been told that you can in fact change the 4 lug axles out to a 5 lug axles and keep the same 7.5 rear end,But would not gain any more durability if ever converted to a built V/8 as I have done,
