Did some more looking .
Well, it seems that any early Holden V8 or chevy V8 eg 350 327 thermo housing top will fit the old 216
Even the chrysler 318 V8 housing will fit . I wandered down to the neighbour and checked his V8 engines out with the old 216 thermo housing.. all are the same bolt pattern
I will buy one on epay ..... Mike
