what front and back uprights do u use on an avon tiger and do u need any adaption plates to use the standard sierra hubs

In the book, they use cortina uprights and hubs on the front, so no need for any sierra gear, but they are kinda tricky to get hold of. They mention using sierra uprights, modified, but they don't mention how and what modifications are required.

The rear uprights are fabricated, either by you or tiger, although, in their usual fashion they're gloriously vague about exactly how you are supposed to and even what material you are supposed to make them from, the hubs are standard sierra.

Try mk engineering, £35 each for drum brakes, £40 each for disk brake uprights. Very helpfull man though.

Ow much? You're avin a giraffe incha? £80 for a pair of uprights, thank god I'm planning on making my own.

how do you plan to make your own? Am kinda interested in doing this also, but don't really know where to start with this

Others have suggested cutting the upright section from the original arm and using that, which is what I'm looking into. It will be rather heavier than it could be, but it should be plenty strong. I'm planning on using cut down 5mm thickness rectangular section, mounting the original mount on the inside inner face of the box, and having the face of the mount protruding through the outer face of the box. I'll then cut the edges of the box and bend them in to form the shape of the upright (and reduce the weight a little). There's a engineering company near me that does loads of farm machinery, so that sort of size stuff is their area, so hopefully I'll be able to blag a couple of short sections from them, or at least not have to buy 6 metres of the stuff, could be pricey.

I used BMW hubs for a project once, and when I was cutting up the trailing arms to retreive the bearing housings/caliper mounts, I measured the thickness of the steel. It was 2.5mm, and had a lot of beam and twisting loads on it.
I currently use 1.6mm sheet for fabricating boxed uprights, or if using open-ended RHS, I use 2.5mm or 3mm, depending on the weight/power of the car.
I used to have a 4X4 V8 racer, and it's uprights were open ended 65 x 35 x 3 RHS. Hope that helps.

Just a little bit of over engineering on my part then!!! I think I'll go for 3mm steel then, still more than you use, but a considerable weight saving all the same.
