This is possibly a long shot.. But can anyone tell me what front driveshafts these are from?

I had them fitted to my cosworth converted 4x4 puma, the inner CV's went and so trying to be sensible replaced them with GGR extended shafts - unfortunately on the first drive my passenger side popped out coming off a roundabout with a bit of power down.. Wasn't impressed to say the least!

I'm now doubting whether the original shafts were actually original cosworth shafts from an escort or saph. Which is leading me to believe these might be XR4x4 shafts?



The TCA's on the car have bodged ball joints on the end.. Puma ball joints I think so wondering whether the track is now wider than normal cosworth.. The car is lowered on 18's for reference.

Thanks
