There is an old racers trick for drilling out drum brakes similar to discs. I would suggest getting purchasing fresh drums and getting them cryogenically tempered and then sending them out to California. This shop has been doing it for decades. Article on drilled drums.
I was at a car show the last month, two cars in my catagory (Street Rod). Talked to the competition a while, real nice guy. Finally he was sort of braggin' about how he had a bit over $50k in the car - NICE '33 Ford Roadster. I did a thorough top to bottom of the car and finally told him I thought the car was great. Next I asked the question....."If you spend $50k+ on such a nice state of the art Rod, why didn't you spend a couple extra bucks for rear disc brakes?" He avoided me the rest of the day, I think I offended. (I've got 4 wheel disc on mine but it is no where near as nice a car as his)
Absolutely right on the drilled drums, they used to do it factory on Vettes with the brake option - Pre-65. I do have a Corvette with drums all the way around, inadequate to say the least. On the other hand I've had Mustangs with a dual bail master cylinder and found them to do the job quite fine. How about the old Pontiacs with the drum/rims?
On a high-dollar rod it's all about the bling so he should have unless he was after some sort of "period" look. Ah, you gave him something to do this winter!
Not mine, it's about the speed. (PM me and I'll be happy to show pics and tell you all about it, it goes against a lot of the teachings on the website - but not all est. 425-450hp and capable of 17mpg). Sorry to veer OT.
IMO, I prefer disc over drum for stopping power, ease of MX and reliabilty.

Most US cars in 1967 went over to a dual bail, all it was is a 2 bails for fluid - front/rear. No big deal except they seperated the front from the rear. If you had a leak in a front wheel cylinder the front bale would go low, rear leak=rear bail low. No big deal really, some felt it gave better stopping power. I don't know though.
yeah , i think its a 50 and 60's american term ,, you know pot heads.
Yes, bale is in reference to the reservoirs but I was referencing the late 60's American cars. The reservoirs are cast into the cylinder itself. Not like we have now where you can remove the plastic reservoir that slides into the "o"-rings.
There are also adjustable proportioning valves for those who like to fine tune their brakes.
Nope, I'm not a pot head though last week 2 houses down from me (1/2 mile) the cops stumbled (literally) across 160 maryjoewanna plants in an underground greenhouse while chasing a teenager through the woods the cop fell through the trap door. I'm not growing on my land, not enough time.
