Because you were all so helpful with my question about the "270" coil. I have a question about reparing them. I have an orginal "263" "B-R" that has a small leak in the bottom. Is there any place that repairs them or are they just some thing to put on the shelf?

Re: C3 Ignition Coil
Jay------
If you have a leak, the chances are that some, most, or all of the fluid contents are gone. So, you need more than just a repair to the coil "can".
I don't know of any place that repairs these things and re-fills them. Presumably, Paul Baker of Goat Hill Classics could do this since he manufactures reproduction coils. However, whether he would do it or whether you'd ever see the part again are questions that I cannot answer.In Appreciation of John Hinckley -
are you sure it's original?
I thought the "BR" was used only on non-TI coils to specify an external ballast resistor was needed. Some years ago, a repro 263 coil was made with "BR" on it.

Re: are you sure it's original?
Many say 'B-R' means ballast resistor, but I've yet to see the proof! Corvette was one of the LAST Chevy cars to abandon the discrete ballast resistor and build the function into the wiring harness.
If memory serves, that change happened with the introduction of the Shark in 1968. NONE of the ignition coils used by the factory prior to this period have the 'B-R' designation on them which is when discrete ballasts resistors were actually used on Corvettes.
So, I'd still like those who say 'B-R' is a designation for ballast resistor to show the proof! The same goes for the 'R' that popped up on the distributor cap at about this same point in time.
The rumor says this indicated something resistive about the cap because it was driving resistive vs. inductive spark plugs. I've found NO DIFFERENCE in the electrical profile of pre and post 'R' marked distributor caps...Comment

Maybe not "Proof", but correlation is strong
Also, as the Chev Service news states, my '69 P&A30 (Rev July'69) shows coils for non-TI:
'67-69 All, Corvette 1115238 w/1.3 OHM wire (stamped 238 BR)
'55-67 All, Corvette, '68-69 All 1115202 w/1.8 OHM wire (stamped 202-12-V)
So maybe they should have defined "B-R" as indicative of an INTEGRAL (as opposed to discrete) ballast resistor in the system.
