Re: 68 Tele pickups?
Wow, I actually am not sure.
That date isn't a peculiar one for telecasters so not many people have deliberately sought to replicate that specific tone from them, unlike the stratocaster thanks to Hendrix. Doesn't mean it is a bad year or time or anything, it just means it's rare. Fender essentially had the same pickup specs on their models post 65 and into the early 70s, so anything within that whole era should be able to cover what you are asking for.
This means, from what I can find:
Staggered Alnico V pole piece magnets.
Around 6.5-7.5 dc resistance.
Plain enamel copper wire.
Lacquer dipped potting.
42 gauge wire for the neck position and bridge.
Gray bottoms.
Copper plated steel plate for the bridge.
I think the Creamery has some 67 style tele pickups that you should look into, but I'm not sure of how expensive they are. Mostly because they are hand/scatterwound while the originals were machine wound.
