I'm late to the party here, but, the 1/2 shaft bolt problem was a BIG DEAL among Ford GT owners about 10 years ago before the cause was found: the 'bolts were made from an alloy that, in affect, caused the bolts to 'eat' themselves internally, become brittle and eventually
self-destruct (snap). (Eventually there was a factory recall issued on 'em.) When these bolts 'let go' the rear wheels were instantly 'disconnected' from the drive train and tranny oil immediately "left the building"...so to speak. 'Very dangerous situation depending on the exact 'driving' situation at the time. Regardless, it was car hauler time.
Bottom line here is, if there's the slightest doubt about your Ricardo having the 'new' or 'problem' bolts installed - replace 'em. (By NOW the internal chemical reaction in the originals should have manifested itself...but..."Murphy" lives...so...)
As I recall, there were TWO separate replacement bolt 'kits' issued by Ford...the 1st one ended up being no better that the ORIGINAL 'problem' bolts. The SECOND 'kit' did the trick.
As was mentioned above, Accufab did their OWN research on the problem and manufactured their own kit early on...a 'kit' that proved to be dead-bang RIGHT ON 'fix it'-wise from the get-go. To this day I'm unaware of a single failure of the Accufabs.
