Have recently spoken to Adrian, and he has sold his Manta A, so can't help you.
I can give you the details for these two Mantas stored in a container in AKL, but they are not great. Not sure you will be able to use them as fairly rotten!
Hi,I still have a rh door window,straight with some rust rh door,whole diff and front suspension for manta a,also 240 getrag with shortened gear selector link and bracket to fit manta a(no driveshaft but yoke spline is standard GM).
