I knew that was coming !!!!!!!!!!:p

i noticed that the roll bar didnt attatch to much, as a result i made the rear hoops of the body support out of 20mm x 3mm seamless tube and braced it down to the diff cage to add extra stiffness

Im using a fibreglass rear end from saturn and this is where i anchored my rear roll bar stays, they are bolted in from underneath with m14 bolts through 6mm support plates plates.
Before anyone says it yes i did put one on the other side aswell :D |
how gooder fit are these rear ends. i have a prefabbed aly tank that sits about 1" in from were the skin would sit, willl this contact with the pannel??

Unfortunately you need to modify the rear end a little to make them fit and a book spec fuel tank wouldnt work.
But a few simple mods gets them fitting perfect and they really look the part. |
Andy is about somewhere and will read this,wouldn't it be sensible to make the rear support tubes to match the rear Saturn/Triton tub,this would make the rear end more structrually sound once again as per the book and offer a little rear end protection also for the fuel tank,can someone enlighten me as to why it was removed other than to fit the Fabby tub.

Then again there is nothing to stop a builder adding some additional 25mm box tubes to create a fuel tank protection cage which could possibly be attached to the diff cage. andy ps, in my opinion of course :) |
I forgot about the mods for the tub :p

Anyone who has built the rear end to book spec with the round tubes and then chopped it off :rolleyes: to fit grp (like i have) will probably agree that the design i have used is a much more sturdy alternative, that coupled with the fact that my rear stays are of a larger diameter and thickness than the book spec should be more than strong enough.
I am in the process of making my tank at the moment and once that is in i may consider some extra protection in that area but im trying not to over engineer things too much as i dont wanna end up at 700kgs on the weighbridge :eek: :D |

I did exactly the same as you, and my stays go to the same place. Looks good, and after a bit of stress analysis (I used to be a 'proper' engineer) turns out to be a fair bit stronger than original, as stresses are dissipated over a greater area. Cheers Adrian |
