Help with Saturn Chassis Back End

[andysredmini]

Im struggling to work out the rear end of my saturn MX5 based chassis.
I have uploaded a drawing on my blog http://2.bp.blogspot.com/-_mpP1kf8gv.../s1600/BE2.PNG of the back end and will hopefully try and explain what i mean.
I cut d11, d12 & 13 to the new sizes and tried to fit them in place as show in the guide but it doesn't work out. It appears that d11 should be cut as original and fitted in the original location but the guide has d12 labeled as d11. Looking at d12 and 13 cut from the guide they don't fit where the existing d12 & 13 fit. the angles shown are the wrong way and according to the drawing i have done are the wrong angle on 1 end.

On the drawing it also shows that d11 (12 on the drawing) doesn't follow the line of plate cp7 on the shock / roll bar mount assembly. should it follow the angle? it still doesn't follow it if i sit it on the corner of the tube and not the diff plates as show.

I also couldn't find a drawing of rp1 & rp2 but i think they are listed as grp1 & grp2 in the cutting list at the back.

Sorry if this doesn't make sense. i have confused myself trying to work it out and more so trying to writing it down.

If anyone could take a look at the dimensions on the drawing on my blog and offer any advice it would be gratefully received.

Many thanks

Andy
