1st, When changing to mechanical tappets rather then hydraulic, do you have to change anything else apart from the cams?? ie guides, stem seal etc

and 2nd, if im fitting a set of gauges and i want to be able to dim them on the same circuit as the rest of the dash,(hope this makes sense) does anyone know what wires i need need to connect to off the back of the dimmer switch?? (its a three door cossie if its any help)

many thanks for any info

 

You DON'T need to change the cams at all when going from hydraulic to mechanical profile.
If as I assume a yb just need 1.8D buckets and shims, direct fit.
To dim the clocks with the others, you can simply hook into the illumination wire, which I think is grey/yellow, but prod with multimetre to determine.
