V6 Mustang propshaft
 

I've just been informed during a pint or two at my pub that MG Rover fitted V6 Mustang propshafts to the V8 ZT/75 models. This V6 propshaft was supposedly only rated to 120 mph so the inference is that the V8 ZT 75 models were "unsafe" from day 1.

Doesn't sound right to me and I've only ever seen photos of crated engine/gearboxes. I'd guess MG Rover would have supplied bespoke units although a google of the part number suggests they may have been a Subaru unit..?

Over to the experts 😊

Ok think I've answered my own question here. Seems the V6 propshafts of the period were unbalanced and known to fail at ca120mph so the V6 Mustang was restricted to a sub 120 mph top speed to save money/lives

Sounds like the usual "all Rovers have HGF" motif has been copy/pasted into "all V8 75/ZT 260's have propshaft failures" one urban myth meets another urban myth. Let's all buy Volkswagen. Wait what?

Here is a quote From Roger on the 260's who if anyone would know he would...

"The 260 drive train uses a standard Mustang GT, Ford built Tremec 3650 series gearbox that attaches to a long two piece propshaft that has a central bearing mounted to the car body before connecting to the Dana LSD (Australian made for Holden's and TVR's amongst others). There is a certain degree of free play in this system and the mass is great as it is intended to cope with up to 500 bhp over the long term, so is under stressed in current form"
