no worries you can pick it up for £12 if you shop about. its actually handy to have the book out in the garage rather than print scraps of paper off and its cool to have the grubby book at the end to gloat "look i built this from this"

as for your transmission tunnel dilemma. you can actually build pretty much the whole chassis without the transmission tunnel and do it at the end once the engine is in. to be honest even on a standard car the tunnel could be made narrower towards the rear as the prop is the widest part.

That's brilliant.

Are all the Sierra diff's the same shape? as in I am currently not sure what ratio diff I would like to use? (any recommendations for the set-up I aim to run?) .. Be cool if I could build it to the spec of the drawings and then choose it later on.

So i suppose the only gain you have from building your tunnel narrower is you have more "person space" in both sides of the car?

Really looking forward to the build. I have the ammendments all printed out ready to intergrate them.

Where would you recommend ordering the 1" x 1" x 16G from? and being as the entire chassis will be made from this, how much would you recommend ordering in length?

Cheers Ash.

Yes, all Sierra diffs are the same shape. (There's the bigger 7.5" diff, but I think it was fitted only to Scorpios). By far the most common ratio is 3.62, but there are also ~3.38 and ~3.9 versions. I think the latter was fitted to diesel cars, and the former to the more powerful DOHC versions. Usually people don't pay much attention to the diff ratio and just use whatever came in the donor.

Search around the forum, questions about steel suppliers comes up quite often. The lengths required were also discussed a couple of times. I used 42 m of 25x25 and ~14 m of 20x20 (19x19 unavailable here).

I will just use what ever comes in the car in that case. If it came in the car its good enough for this

Thanks for your measurements. Maybe if I order a little more I should be okay. round it up to the next 10 or something.
