Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Attaching old front susp sub frame to new chassis

Hello everyone
Interesting thread especially the castor angle chang while mounting the front frame.
I am also about to attach the old front to a new frame of my 1965+4 and was thinking of changing the castor.
I am not clear as to what you call the cheeks of the frame.
Can you please elaborate the castor change by the mounting of the cross frame?
Thank you in advance.
George
