Thanks to everyone who has responded to my thread.Obviously it's up to you but nothing goes wring with the starter apart from the solenoid contacts, it's easy to take the 3 screws off the solenoid cap and pull the solenoid out and replacer the contacts with the starter still in the engine, done it loads of times (disconnect Bart first lol)
Hi,Take off the positive cables go on the solenoid both sides the take off the half nuts left on the studs, then push stud and should fall out into the plunger chamber take out and fit the new ones
