Take the arm out of the car or try and drop the arm down a bit.

a mate of mine had this dilema, so he bolted the passenger side and welded the drivers side.

Right angle drill - you can get them in an air drill variety too.

THey aint cheap to buy... I looked into when doing mine. I just relented and got someone else to do it who had the tools.

Don't weld.. engineers don't like welding. A high tensile bolt is easier to pass off strength wise as some blokes welds.

Yeah I had to use a 90deg drill which had a max chuck size of 10mm and then use a rotary bur to open the hole out to the required size. The drivers side took me about 2 hours to do, passenger only 15mins or so... :bad-words:

Stupid question time, why do you need to drill out the diff brackets?

I've never looked into castor brackets before but always just assumed they used the same size bolts as on the standard radius arm setup.

Cheers. :D

with radius arms whern lifted the castor is upto shit, and pinion points upwards, the castor plates rotate the diff back to factory specs,

so the castor plates ave 3 holes, one for the original rear bolth, one for the radius arm bolt, and one, to mount the front of the plate to the diff,

a pic would explain this better, so i might do it later unless someone else beats me,

sorta hard to explain, ive done the best i can at the moment

Sorry, maybe I wasn't clear. I understand the concept of castor correction plates, how they work and why they are needed.

What I wasn't aware of was why the original diff mounts need to be drilled out? I always assumed you just used the same diameter bolt (just a little longer) to bolt the plates on. Thought it was a straight bolt-on, no-mod job.

Ooooooook, so basically you need to drill a new set of front holes higher than the original front hole locations.

Fair enough ...

You will get the shaft touching the crossmember on full droop or when turning hard right at speed (if you have the hubs lockedd it can sound like a shagged out CV if the front shaft balancing tab is right over the crossmember).

I did a temporary fix by adding about 10mm of spacers (washers) between the crossmember and the chassis. The best solution is to notch the crossmember.
