I am looking for the spline sizes for the NA 4-lug, NA 5-lug and TII for both the diff and hub side. If anyone has the info I would greatly appreciate it! Thanks!

 

I know someone has there car apart!!! lol

 

I have completed a 4 lug to 5 lug conversion on a '87 FC.
I have four spindles/rotor/dust shield assembly, four calipers with pads (from 4 lug setup, four-4 lug factor rims 14" in a box.
I have pictures of both sides.

PM me your email as I can't PM reply to you if you need dimensions on any of these parts. <20 posts can't PM.

Are you looking to purchase parts or need dimensions only ?

 

Right now I am only looking for dimensions, if they are what I am looking for then I will be looking to purchase. Just post the info up here, then we all can have it and that gets u one more post :P

 

I have a 1987 FC 4 lug spindle/rotor assembly is in front of me.
I count 28 peaks/splines in the spindle with a diameter of 1.25 inches.
so the shaft would have 28 valleys.

 

I hate to ask this again, but I lost the info. What michaeljgondek posted woulbe be a 28spline/28.57mm that does not sound right...maybe 29mm??? Can anyone confirm this?

 

The 4 Lug,the Five Lug,and the TII half shaft Splines(into the Spindle,HUB assembly) are all the Same size..That is why you can change the Spindle assemblies on the 4 lug TO five lug,on teh rear,to get the Bigger Brakes,and NOT have to Change the Half Shafts..the TII half Shafts are Thicker though,to Hold more power,and they Won't fit On a Regular OPEN or LSD N/A differential.the Bolt patterns,I believe are slightly Different.

 

If you want to do a brake conversion, the 5 lug crap will fit on the 4 lug, if you want to do a Turbo drive train, then you will need to get a Trans, driveshaft, diff pumpkin, and axles, but the hub area is all the same.

Note: The T2 has slightly wider rear calipers, because it utilizes vented rear rotors. Some of the NA 5 lug cars, while having the same 4piston front brakes, have solid rear rotors.

 

Thanks guys but I am well aware of what can and cannot be swaped. I am simply looking for the spline size.
