Dont get the newer maggies they are kack, mine lasted about 3 months then the tpa stripped so i coudent adjust it, then i bought the older style lever as you cant by the tpa on its own, then i sold the maggie lever and bought an RB desing lever and have never looked back it is so good and dosent leek. so yes stay with the levers you have got as they are better then the newer ones and if you want to make you brakes better buy fresh products levers and but a four bolt booster on the back, maybe a grind and some good pads or some soft pads and some tar.
