I know a gent with 4 sets of cortina running gear (front uprights and back axle) up for grabs. Ideal for those building a book car. And I will gurantee you will pay much less for uprights and axle than some kit companies and ebay sell a pair of uprights for!
keets (k33ts) had a set off the gent last time he had some and was very pleased with what he got AFAIK.
The parts are located in the peterborough area, so reasonably central for most people.
If anyone is interested let me know and I will pass on the gents phone number and details.
Cheers,
David
