Early series 3 engine compartment layout

I have just finished a complete restoration of an 83 series 3 and enjoyed it so much am starting on a 73 series 3. The engine bay has been altered over the years and I am looking for pictorial reference showing me where stuff should be, particularly in reference to layout of non servo braking and carburettor/ air cleaner.Thank you in anticipation.

Got pics of a 74 109 (ex-military) but while it was originally a petrol it has been converted to Diesel...and has servo-assisted brakes.
Can post if you think they might still help..or wait until a petrol owner happens along.

Thank you, for the moment I’ll wait to see if a petrol without servo comes along

It did occur to me that if anyone in North or mid Cornwall has one I could photograph?
