Pics of rear disc modifications
Has anyone got some pics of the adaptor plates you can get to convert drums to discs on sierra rears? Preferably fitted ones.
It looks like I need to chop off the lugs on my disc hubs and make a plate to bring the caliper closer to the axle centreline as the std brackets foul
the caliper and it needs to go another 7mm closer... doh!
This is all because I wanted to use 240mm fiesta rears rather than the mahoosive 253mm sierra ones. Plus it gives more clearance to the wheel 
On another note, anyone know if there is a difference between drum hubs and disc hubs other than the caliper brackets?
Thanks,
David

You're supposed to be an engineer?Draw it. 
I would think that the bracket needed would be straight forward. Make a flat plate, then add some suitable thickness bosses to put the caliper where
you want it.
I'd show you what I did, but it's all incorporated into an upright, so no use to you. The vw/Audi/Seat calipers I used weren't
identical either, though off the same car.
Cheers,
Nev.

Drum hubs are smaller and lighter than disk hubs, they use different bearings, and have tripod CV joints. They don't have the
"ears" to bolt the calliper too.
They have the same 4 mounting bolt positions so your upright is the same.

For info, when I was throwing a 2wd Cosworth back end in but keeping the drums all I did was chop the lugs off the hugs. Everything else was
interchangeable.

Hi David the brackets provided by MNR they place the caliper at the rear which hits the De Dion or the front which puts the caliper upside down.
I had 3GE components make me one to put the caliper at the top

I can draw it up no worries - i was most interested in which side the plates bolted on, I seemed to recall them fitting behind the hub rather than
infront of it, so I was obviously thinking wrong!
So thanks for the pic chaps. I will post up some of what I have done this afternoon in a mo...
