Funny you had condenser trouble. I just did the other week with my cmp truck. Thankfully I was only dead in the driveway. It had been running rough before hand though. Anyway I did some searching on the vintage chevy forums and found a guy…..he was frustrated with the way modern condensers are crap so he found a different product to replace them. Hey are made to fit inside the Chevy distributor. However they would work just fine for the flathead as well. I bought 3 from him and they arrived the other day. I installed one in the cmp and what a difference. Lots of power and a very smooth running engine. I took the truck for a drive and was easily cruising along at 40 mph.
Anyway here is his contact information.

He sells them for $12 USD each plus shipping. My 3 came to $46USD.
Here is a bit of further reading on his product
