Hi Andy
Not sure what happened to my old Bagheera as it was on ebay looking very sad about 2-3 years ago by someone in Preston. I suspect it was broken for spares.
The reg number was LUD15S and I had fitted a 1.6 Solara engine and a low geared diff from a 1.3 Horizon.
Someone out there somewhere might still have the gearbox....
Might be easier to find than a Horizon 1.3
