Hi Guys,
I hope someone can assist with a few questions. I'm working on a 1968 Triumph Spitfire for vintage racing, the cars in this group are pretty stock, so no real modifications are allowed. Anyway, my questions pertain to the rear suspension.
Spitfire swing axles tend to break so I need to address this issue.
Do the axles break or separate from axle flange? I saw in a forum were the flanges were welded, is this correct? Or are they just too weak and they snap mid shaft etc?
I know that GT6 axles are a good replacement, but I also heard that VW and Corvair also work well. Does anyone know what year VW works and are any modifications required?
To reduce the swing-axle jacking effect.
Adding a pillow block between the leaf spring and rear to straighten the leaf spring, is this correct? And where can I buy one?
A Z-bar should be installed. I've looked everywhere but no luck, does anyone have any ideas were I can buy one or do I have to make it myself?
Shocks installed upside down to reduce unsprung weight
Please see link below, this is an example of a car that uses most of these suggestions.

Hi Rick,
It might also be worth looking at

I picked up a block for my 70' leaf spring off ebay. Be careful when looking for one though. They changed the bolt pattern for the leaf mount on the diff in 71. In accordance to PRI, don't expect your part to arrive any time soon. It seems like they start making things when you order them.
Guys,
thanks for the info I found plenty of advice at the triumph experience site.
