Does watts link length matter?

Hey guys!

Building a new rear 9" axle for the Rolls Royce and stumbling around on building the rear 3 link.

Axle WMS is roughly 62"
Lower control arms are 42" apart
upper 3 link is 6" off centerline
Using a 5" watts link bellcrank mounted to the chassis.

I have the option of running the watts link mounts inboard the coilovers or outboard the coilovers.

Inboard gets me around a 28" watts link length (2 - 14" arms)
Outboard gets me around a 52" watts link length (2 - 26" arms)

Inboard is much neater and easier, where outboard won't turn out as nice and have a few clearance issues.

Any ideas or recommendations?

The Watts arm length will determine how much axle travel you can have. If you get enough travel with the 14" arms, use them. You might have to mock it up to check.
