By sheer luck I ran across a chap named Kev Baker at a swap meet last year. Kev runs a business called K B Classic parts at 2 Margaret St. Witta via Maleny and describes himself as an "Automotive Electrical Parts Consultant and Supplier."
I had been chasing a couple of those fine thread nuts for my Lucas spotlights which are standard on the MK 1. Every avenue seemed to be exhausted when at a swap meet Kev was pointed out to me by a Victorian electrical parts stall holder as the "Giru of Lucas parts in Australia". I approached him and described my problem. Within a couple of weeks I had the brand new nuts at $ 3 each. Another club member had been chasing a new distributor cam for a MK1 with no success. I contacted Kev and he immediately came back with a confirmation of availability and price.
While I urge support for the suppliers who advertise in this magazine you might consider using Kev Baker for those really hard to find electrical parts. He specialises in mail order and is available on phone 0754 944 221 and fax 0754 944 114
