My .02 cent. I installed a Newport electric on my 52 panel and it worked like a dream. All good.
.....its been a while but if my memory is correct, ( I could check receipts) but there are two numbers for them. The one i used stated it did not interfer with the choke, or vice versa, and the number had a "C" at the end of it.
Go ahead and spend the money on a good one. Do it once, do it right because it taint easy to work under the dash!! I think I made one small adjustment at the wiper blade and never had a problem the 7 years I drove it.... and yes, I drove it in the rain quite a bit.
