Hi, it sounds like a very early KVA if its got VW rear brakes. The first ones I seem to remember had VW Variant rear hubs and brakes, I could be wrong so check with others. By the time they got to mine, chassis No 61, they were using Mk1 or Mk2 Ford Granada rear hubs and brakes. The thing with early KVA`s was that you were left on your own to use whatever you could find or wanted as they famously came with no build manual. Hope this helps. Kev
