Will do. I'm looking at sourcing most parts online. Roadster Factory, Moss, and Victoria British seem to be the most popular. Would you lean towards one business? Quality/price fair at most? Following the guide you provided, I need to replace hoses - 5/16" hose at Napa should work for fuel right? Can I get away with a Napa radiator hose? Do you recommend a specific antifreeze for the 1500? It gets -40 here in the winter. Would it be worth it (at my amateur level) to get electronic ignition instead of points? What about spark plugs? Is synthetic oil acceptable for these old cars?
So many questions; all good ones! Vendors first.
The Roadster Factory is arguably the best of the three you name, with prices usually competitive enough. Moss is the newest player in the Spitfire game and, IMO, is still feeling its way around. Victoria British is, in some ways, the JC Whitney or Western Auto of parts for British cars. Lots of good stuff, lots of less-than-good stuff, tech support well towards the lower end compared to other vendors. Two others very worthy of note and business are Spitbits and TS Imported Automotive, both for price, availability of parts AND technical advice.
NAPA or other generic hoses are ok-ish for radiators (although it's really best to have a hose with the built-in flexibility for the top rad. hose). Fuel hose from them is just fine; so is heater hose IF you can fit same without kinking the hose (some hoses are best replaced with correct molded-to-shape hoses).
"Classic" old-time antifreeze is just fine; nothing special needed. I tend to prefer quality conventional oils simply because leaks tend to make the cost of synthetics even higher. If you've got a well broken-in, leak-free engine, synthetics can be just fine.
I'm a points-and-condensor fan, too. Best argument I can make for a Pertronix or similar electronic ignition update is that it's tough to find especially points for Delco distributors that are worth the packaging they come in, let alone functional and durable in their own right.
I'm a Champion plug fan since...forever, although I also like AC plugs in these. Honestly, I think choice of BRAND of plug is more closely related to your own loyalty or whatever your dad / uncle / favorite corner mechanic swore by than it is to any scientifically proven reality!
