I looked, but, I don't seem to have any. Layson's lists reproduction lenses on their website. Kinda pricey, but, other lenses I've gotten from them have been of good quality. Good luck!
IIRC, those were used on marine, industrial, and maybe some vans/motorhomes where you couldn't see the timing marks with a conventional timing light. That tube was for a magnetic/optical pickup type timing light.
I assume this is not a wagon? I've never seen one with actual chrome. All the ones I've seen (on the 270 and GT) have a glued-on plastic trim bezel piece with some silver foil on the inside to make it look chrome-like. I don't think the 170's came with that bezel.
If you have an 8 3/4 rear end, the most common number is A7. Bower/BCA also made a kit with A7RK for the right (passenger) side, and A7LK for the left side. Do you want the factory Mopar number?
I have a new M & H harness with the Mopar electronic ignition conversion if that's something that works for you. I bought it by mistake a while back and would be willing to sell it. PM me if interested.
