After much trial and error I've finally got all this to fit together and I think it will really improve the look of the car. Probably won't make a lot of difference to the braking performance but it was really the look I was after
It's a combination of 145, sud and 33 parts plus a small amount of fabrication and machining.
Parts required are:
145 or 33 P4 calipers, mounting frames, back plates, pads
33 P4 hand brake cables
Sud drums machined into hubs
Custom made brackets (8mm steel plate)
I've pretty much replaced everything with new or reconditioned parts including wheel bearings, caliper slides, high tensile bolts. The downside has been the cost ..... £470 !
If you can find good used parts and someone to do the machining and fabrication cheaply then you could probably do it for half that cost.
Still think it has been well worth it and if anyone wants to do likewise I have the drawings for fabricating the brackets
