After a prolonged search for the wiring clips I was telling Phil about the other day, I came up empty and was begining to think I must have been mistaken about ordering them in the first place. With that in mind, I located another source (ebay, not MacsAuto this time) and ordered 2x sets of 12 pieces each. At $5 per 12, it's not a huge investment and I really do want to use these.
Made the purchase yesterday, sent a request for seller to advise shipping cost, then waited for reply. Seller got back to me and shipping cost minimal. Purchase finalised this afternoon.......................................

.......then I found the 10 pieces I did in fact already have. They were in the proverbial "Safe" place.
