Sway Bar Link Bushings - Odd One!

Rebuilding my pretty dusty and tired looking front 308GT4 suspension. I did the rear a few years back, and it was definitely "In-need". Ordered up all the suspension wear items, and packed the shocked off to Truechoice (who I might throw in a plug here has only done the most competent work restoring my Ferrari shocks).

Anyway

The sway bar rubber link bushings (not talking about the "silentblocs) are too small. The taper on the rubber is fits loosely in the hole. The originals are slightly larger. Looked up PN's, and they are the same rubber bits used on many-many cars! I checked the '74 GT4 parts book, thinking maybe it's an older car, but same PN?? The links look different from other front links I've seen. All the others I've seen (GTS, GTSi, Boxer) look like cast Aluminum with a "red-cross" looking X-section. These look like forged aluminum with a round X-section. I'm certain these are original - absolutely. Way to many other bits in there to attack before you get to the sway bar links - assuming someone would have monky'd with it. Do I have the ultra rare hi perf links (or low -perf ) components??

Just thought I'd bounce this off other F-chatters.

Thanks for any input

 

Got hold of a newer ~79 ish GTS sway bar links and discovered spacer tube
(1976 parts book FPN#108998 tubo distanziale vs 1974 parts book FPN#100985)
thru the rubbers is shorter by 2.1mm.

Now - Was this intentional by Ferrari? Was this finely engineered into the front suspension to allow some suspension travel before roll forces transferred thru sway bar ??

Any huge GT4 fans out there observe this?

I'm inclined going to the newer (shorter) part.
