9inch into xe

[S-Pac Jake 9]

Hi All. 
 

I’m putting a 9inch into my xe falcon and have a couple of questions about fitment. 
Got the diff all together and have decided to throw it under the car tonight.

After throwing it in I’ve noticed that my watts link arms come bent after the watts link is fully seated onto the diff. 

I’ve also noticed that if I jack the diff up into the car the watts link eventually hits the tank strap mounting point which ends up in the middle of the car.

Just curious to know for those who have done this conversion, how they got around these issues. Thanks a lot for time fellas

Hey mate check out my thread on my xe I had custom watts link arms made. Not sure about your fuel tank clearance

Hmmm......... your diff is out of a coil sprung Falcon.??  No reason why it won't fit. Standard fuel tank??  Does it clear when sitting on its wheels.??

pretty sure BGDAV's 9" into XE has the watts link bars at an angle now. doesn't seem an issue

 can it be trimmed a bit? i vaguely recall it needing a bit of a trim. been years since i've seen that car though

 

 

could have a look through the thread

Did a bit more mucking around under the car. I’ve got the car sitting pretty low, hence my issue with it hitting the fuel tank strap mount. Just moved the tank strap mount point back to help with clearance. I’ve got another set of wattslink arms that I’m gona angle the ends on so they sit straight. See where I’m at once that’s done. Thanks for the information fellas.

Both rods the same length.??  Got them the right way round.??

if it's low you'll probably have issues with the tailshaft/diff parts hitting the floor. BGDAV fitted a bump stop on the nose of the diff(bolts on to uni joint area of diff)

they are straight normally (borg warner diff) the 9" puts the mounting a few inches further back towards the fuel tank.

I literally left them on the car when I took the borg Warner out for the nine inch so save way round.

I’ll see how I go I’ve got a bump stop ready for it if need be
