Wow. The luckiest finds was the smog system, now $2000-$3000 restored from Bill Hodel, and the 1972 only T-3s are a bit difficult but I have found them at salvage yards. Those dated tipped fan blades are hard to find. GM made service replacements through the early '80s but are no longer in production. Those had numbers on them that appear to be date codes but not. I bought a July 1970 one for my March 1970 built car and be darned if a January 1970 one didn't come up for sale on the Corvette Forum so I got it and then sold my July one to a guy who needed one for his August built 1970.
I thought the wheels on my '70 were 1970 AZs an then I discovered that the darn things are 1976 rallys. Depending on the dates on yours if you come across '72 rallys let me know about your '69s. NCRS doesn't judge the wheel date codes on the ones on the ground but only in the tub.
I'll check with a couple of sources on a 1971 July-September 1100544. I haven't dealt much with kick down solenoids. Is that the same thing as a TCS relay? The radiator tag is not a NCRS judged item according to what I've read on the NCRS Technical Discussion Board because they are often in a difficult place to be seen, fall off, or deteriorate.
Oh, boy....those 287 B-Rs are tough to find. There was a guy on eBay who told me he had one for $200 over a year ago and I cannot find that email. That was the last one I had known about. I believe that Dr. Rebuild has those steel vacuum lines unless you hope to find an original.
I have three sets of correct, dimpled chrome valve covers for the 1970 LS-5. There are specific characteristics I know to look for. I'm glad you went to the original painted valve covers. Do you have the dual snorkel air cleaner?
Okay, you need a September 1971 tipped fan blade and 1100544 alternator and rally wheels, a 287 B-R coil, a radiator tag MH, steel vacuum line, a carburetor solenoid. I'll keep a look out for you and will contact you from time to time when I find things. My direct email address is
