Solid flex disc?
Solid flex disc?
I put cardans in. Without a dual mass FW the vibrations at certain engine and vehicle speeds is horrible. it's best to just use at least one rubber flex disc of adequate size.
It is best to convert to a one-piece driveshaft with U-joints and a slip yoke using a yoke adapter for the transmission and differential (Spicer part number 3104-27), as shown here:

A 2005-13 Ford Mustang driveshaft already includes a slip yoke and is easy to find (not sure about the UK though), so it makes for a good candidate. It just needs to be lengthened by a drivetrain shop and used with conversion U-joints, since it probably comes with 1330 or 1350 joints, while the 3104-27 yoke uses a 1310 joint.
