Hi guys can anybody help me with the changeover date from metal Lockheed master cylinders for brake & clutch to plastic, or close to for a Cooper S. My June 69 S has the original Lockheed brake booster, that I have had restored, this makes me think that I should have tin can master cylinders to maintain originalty.
Cheers.

Hi Kath. During 1969 the Mk2's used up the last of the Mk1 Master Cylinders, Boosters and Heaters. I have seen a few 1969 Mk2's and the earlier ones had both tin type Masters. the later had a plastic clutch and tin brake. There doesn't appear to be any hard and fast rules. Here is an example of a very late 1969 car owned by Len Nation. http://www.tradeuniquecars.com.au/featu ... -cooper-s/ This is car YG2S4 1237.
This thread is worth a look as well, viewtopic.php?f=2&t=37145&hilit=hose+clamp
This car is only 6 before yours but has had a restoration so it may have had the Lockheed booster originally. http://www.minimania.com/cars4Sale/1251 ... er_S_Sedan

So - After all my waffling on. I reckon yours would have had all the MK1 bits.

Thanks Brad, mine is actually number 80 a very early one. Built around 5th or 6th month 1969, so do you think that it may have had the tin cans? The heater is the original & it is the metal heater.
Cheers.

would definitely say tin types. I have an early mk2 - around car 330 and it has tin tanks mk1 booster, mk1 heater, thin flange block, etc etc
