A cheap axle swap that is easy to find for 67-68 mustangs is a ford explorer rear. It's the best deal, many came with 3:73 and limited slip, and early ones came with drum brakes others came with factory rear disc. The width is perfect no cutting, you will have to move the axle perchs.

Thanks for the reply. I found out yesterday that the guy I bought the C4 from, also has a rear end out of a 68 Mustang. So that should be a direct bolt in. I am actually leaving to pick it up in about an hour. :thumbsup: I will post pics in a few days. :thumbsup:

How does this sound for a tire setup? I shouldnt have too many rubbing issues with these sizes.

235 40 17 IN FRONT.
275 40 17 IN REAR.

Welcome back Adam. Sorry to hear about the back issues but it sounds like every thing is headed in a positive direction over all. Can't help with the parts you need but I do like the exhaust you plan on using for the car. Good luck!

T/y
Looks like this 68 rear end will be a direct bolt in. Even the driveshaft fits perfect. But I wont be bolting this into the car until later after we get the car rolling or if the 14" wheels and tires sell.

Sheesh I didnt realize how wide the rear tires were on my 69 Camaro until this pic.

Some interresting results after dropping the engine down last night off the engine stand.

74 Flywheel 14"
74 Torque converter holes 11.5"

68 Flywheel 13"
68 Torque converter holes 10.5"


Soooo the 74 flywheel on the engine will have to be removed. I am going to try the 68 Flywheel and torque converter on Thursday to see if that will bolt up. It that works I will have to try a 68 Starter and hope that will work.

Some more information I found out is that the 67 Tranny I unbolted from the straight 6 would have worked IF I bought a different bell housing. Cant believe how much these 2 trans look alike considering one trans was on a straight 6 and the other was on a 289. Sure seems like they are both C4 trans to me.

This number is on the front of both of them.

Now for pics.

Check out this link for wheel and tire fitment for early stangs
You would be surprised what you can fit on a 67/68

Thank you that is VERY helpful! For the front 2 tires I will try to find a used set of (2) 235 40 17 since the front wheels are 8 inches wide. :thumbsup:

Hey Adam, welcome back, sorry to hear about the back, nice to see you workin on the cars again, congrats on the wedding, Just did the same thing in April,

CAMAROBOY69 08-19-2011 08:22 AM

Thanks Steve. My back was the easy part. Its the Vertigo problem that requred surgery and has been a constant issue.

Spent about 4 hours in the garage trying to piece this together with all the different bell housing, flywheel, and tranny combinations. After several mock ups, I finally got the flywheel, bell housing and starter to work. But it required quite a bit of modification to the spacer bracket that is between the block and the flywheel. I ended up drilling some new holes in the spacer bracket and re-located the starter hole by about half an inch. Thats what the cardboard starter template was for. After doing all of that it worked!!! The starter bolted up in the proper location next to the flywheel and the bell housing bolted on and cleared everything. In fact I used a jumper box to actually turn the engine over last night!!! :)

So now that the everything bolts up and engine turns over, I just need to get the broken bolt out of the back of the block and get a few more tranny bolts. Then I can put the engine and tranny into the car. I also bolted up the Polyeurethane tranny mount right before I went in for the night. Very productive and exciting night. :)


68 Flywheel bolted onto 74 engine but the 68 starter is about an inch from the flywheel because of the 74 spacer plate.

Time to modify the spacer plate so the starter fits closer to the 68 starter.

Starter bolted up after spacer plate is modified. Had to relocate the starter hold and had to drill out several other holes so the bell housing would bolt up to the back of the engine and still have the starter bolt up. Perfect fit!!!!

Used this jumper to turn the engine over.

I can only post 14 images so here are the rest.
Spacer plate and toque converter installed. I will reinstall the starter again after the engine and trans are in the car.
