SPF Pertronix 1185LSC Electronic Ignition 1953-56 Buick

I have a unused Pertronix Ignitor kit, 1185LSC that I bought probably 20+ years ago for my 1955 Buick. Never used as I converted it to a Dynaflyte dual point distributor instead.
These are $144 on Pertronix’s site. Shipping will be by USPS Priority Mail whatever that runs.
It fits 53-56 V8 Buicks and possibly some of the straight 8’s but I’m not too sure about that.
