Fox Body Drive shaft

I read here a while back that you could swap a fox body diveshaft into the Mav (2 door) only needing to swap the slip spline from the mav's driveshaft onto the fox's. Well I picked one up (fox driveshaft) and have a problem/question.

The U joint on the fox drive shaft is longer/bigger that the mav's u joints. How do you get around this?

The problem I'm having is that the fox u joint won't seat into the u joint carrier on the 8". It had locator tbas and the fox u joints stick out past the tabs. I had planned on buying new U joints anyway, but obviously the fox ones wont fit. And It looks like the mav ones would sit too far into the yoke on the fox driveshaft.

What to do, what to do????
Thanks guys

 

DUCK TAPE

 

sorry i cant help you but whats the advantage to fox drive shafts? are they lighter or something?

 

aluminum i believe

Limeade is the man to talk to

 

cool, i remember someone here pulled an aluminum shaft out of some SUV or truck any only had to pay to have a few inches knocked off it and it bolted right up

 

mine seems to be pretty heavy duty feeling. I don't know what it's made of, it's pretty heavy, I think it's out of an '89 GT. Seems to be a bigger diameter than a stock maverick one. About the u-joints I'm not sure. Mine's mustang from tranny back

 

The fox driveshafts are steel. You can use the stock mustang one or the FMS aluminum for the same DIRECT replacement of your maverick one.
The solution to the u-joint is get a 3 1/2" to 3 1/4" u joint. I have done this already.

 

Can you clarify what you mean with those measurements. Do you mean 3 1/2" x 3 1/4" u joint?

Or do you mean I need a 3 1/2" to 3 1/4" like as in a scale of sizes?

Thanks

 

Eddie what he is saying is that they make a u joint that fits your application with a span one way of 3 1/2 to fit the Mustang joint side and a span of 3 1/4 to match the Maverick yoke.

 

Exactly. I bought a good quality spicer brand. The autozone fools wont know wtf, so go to driveshaft shop or maybe napa. Dont bother telling them "what vehicle", say I want a 3 1/2" by 3 1/4" HD joint.
Dont forget to grease after install.

 

nice car there shiny

 

NICE!!!!
Thats what I needed to know
I'll check napa tomorrow to see if they have it.

Thanks all
Thanks Shiny

 

THE BRAND PRECESION PART NUMBER IS 331 OR 347. I can't remember other than it was a stroker kit number....
