Ace font wheel cylinders

[pjbowman]

As it happens, now I need to also replace the front wheel cylinders on AEX127.  Does anyone know if these are the 1" bore, or the 7/8" bore? Both were used on the AH BN1 which is what the interchange lists calls out, so not sure which to order.

   Front wheel cylinders for Drum braked Ace ...7/8 "
   Rear  wheel cylinders for Drum braked Ace ...1"
   
   Disc braked Ace have 7/8" cylinders to the rear.
   
   ACOC Spares often have original Girling units in stock, if not try Barry Howsley, both address in ACtion Magazine.
   
   *** Caution regards Chinese repro units, better pay extra for NOS Girling units. (personal view)

From the Girling list, part number 390320-1W.
   
   7/8 inch bore.
   
   These come up on ebay, but I don't know what the quality is like. As Keith says, only buy the best!
