Converting 68 Valiant Rear to use 15" wheels

Only just coming back to these replies now. Thanks for all the help thus far!

Is the disc brake conversion telling you that you have to run 15" wheels for caliper clearance, or are you being told that by someone else?
For the fronts, the seller told me I'd have to run 15in wheels while for the rear, I'm going of the stats listed on the page that says "Minimum Recommended Wheel Diameter (in.): 15 in".

The best route would be-find a A Body 8 1/4 rearend or a 73 up 7 1/4 if you are staying with the Slant 6. It sucks having 2 different wheel bolt patterns on your car.
I guess my question sort of is why exactly finding another rear end would be the "best route". Are you figuring that between the 2 kits, the wheel bolt patterns wouldn't match up? I'm new to A bodies so this is a genuine question. Hope I'm not coming off as argumentative or something haha. Thank you for all the information though!


For the rear.
You can leave it at 5x4" and get 15" wheels to maintain the look of the front

You can replace the rear, many options that will get you 5x4.5"

Do a disk conversion that changes the bolt pattern to 5x4.5"
Thank you for breaking this all down I really appreciate it.

Yes. The car is new to you. Make it drivable and enjoy it for a while. EVERYTHING you have talked about is EXPENSIVE.

Then do the research on front disk conversions, there are other options than aftermarket, that will bolt on (like OEM parts). If it has 13"wheels you will have to swap out to 14" minimum.
This is a great point also. There really is no rush to get this done asap so perhaps leaving this for further down the road isn't the worst idea.

you can buy 15 inch 5x4 brand new still
Thanks for letting me know, I'll have to look around at where I might be able to find tires for this.
