KK, I don't think you can do much about this assuming everything else is set up correctly. You must have a 1500 that has the steering lever that is slightly bent at its end, the later 1600 is virtually straight. Some members with 1500's may be able to comment but I can't see that it's a problem. Barney describes the various types of lever.

Spot on. Looks like you have a 1500 type steering arm. See here: http://mgaguru.com/mgtech/steering/steering.htm
Could be a 1500 chassis with disc brake conversion, or a 1600 with some retrofit 1500 knuckle and arm.

I seem to remember that my car (1962 MK-II) had spacers behind the dust covers on the front brakes. They were like a thick washer. I don't remember just how thick they were but it may have been there to prevent the rod end from touching the dust cover.

ThanXX You are all spot on its a 1500 conversion ...

looks like Im on the lookout for some later Arms ..

Seems to me that the different arms must wind up with the hole in the same place, else there would be different racks or tierods to compensate. I think the later version with the offset at the base is simply easier/cheaper to forge and possibly stronger. The contact of the boot is probably because of differences in rod ends by supplier, it's pretty common. Or see below.

Early 1600 did not have dust covers. The final edition of the WSM says that dust covers were fitted at 102589 disc wheels and 102929 wire wheels. Reference includes mention of new bolts HBZ0611 and distance washers BTB386 going on before cover plate, no picture. "The covers may be fitted in sets to earlier cars."

If that steering arm is early 1500 you will also need the later knuckle. (Drats, foiled again). The change came at car no. 54247 July 1958. Early arms had 1/2" UNF Stiffnut, either Aerotite or Nyloc style, and no washer. Later arms had 5/8" UNF Stiffnut, Aerotite style and a 5/8" flat washer, zinc. The different arms require different mating knuckles. You can tell early from late by size of the thread, 1/2" or 5/8".

DRAT....FOILED AGAIN Under statement or the week..

Now I thought that I had done my research on the conversion.... :0(

If I just leave it as is will it give me any problems ??

or am I going to have to find the later Knuckles..??

Suppose I could remove the Dust shield and give myself a couple more MM clearence ..

Read what I quoted from the WSM again. You should have clearance between the disc and the shield. Fit a couple of washers between the shield and the caliper adapter bracket, with suitably longer bolts (unless you already have the longer bolts).

Hi FRM, thanX for that ... All the ref codes I have to hand are from the MGOC spares book and they dont seem to tally with yours, ( I have several other Ref books ..moss etc at the garage.. 40 mins away)..

I Bought New (special) fixing bolts for the calipers + Brake hose support bracket + distance washers for the Dust shields.. so think that Im in line with your comments ..Unless I have put them together wrong..

( Ok this would not be the first time..so will re check)

will report back as Im at the Garage in the next couple of days ...

Dust shields on disc brake/wire wheel cars in Australia are not common at all. Are they of any use?

Ken -
Those are factory numbers. I think there are factory parts lists online, maybe Dominic or Barney sites. Distance washers go between the caliper bracket and the dust shield. They move the shield toward the disc.

Mike:
Back when we could compare cars with and without in regular service in rain and snow, cars with shields had much better disc condition on the inner face and less pad wear. We thought it had more to do with slurry thrown up from the road than "dust" per se. But for those who are where it is hot and not a swamp, no shields is the way. In fact, given the low mileage/fair weather use of these cars now, the shields are probably of little use.
