Hi Nev,
You dont mention what state your car is in i.e complete or disassembled. l have a 1957 plus4 on the road which may benifit you to see and a 1970 4/4 in bits that i am rebuilding from which you can see how the "the hidden " bits fit together.
I am in cleethorpes Lincolnshire.
Send me a pm with your phone number and I will ring you if you want.
The beauty of the older Morgan is that they are simple and everything bolts together.
I don't profess to be an expert and certainly not a mentor but if I you think I can help in any way feel free to ask.
