I just took a steering rack I found in the scrap to the shop and exchanged it for a Mk2 Escort rack for the princely sum of £15.96+vat. Beats second hand prices on ebay and waiting for delivery.

what shop was this mate?

Local motor factor. I found some cheaper ones but they are postal.

They still seem cheap prices. The surcharge is a bit poo though...
