SH-1b would accomplish same thing, and line up better, than a pair of TB-1b's. That's what I'd do for Plaid sounds.
Hairpick appears to have been PATB-3/PATB-1n.
He seems to have preferred the PATB-3/PATB-1n set back then, as superpete posted.
Could even try PATB-3 in both positions, to split the difference in approaches. Or ask the Custom Shop to do a PATB-3n (neck-spaced PATB-3), if you are concerned about perfect polepiece alignment to perfectly minimize string pull. [Not likely to be a perceptible difference, so hitting CS over that is probably more an issue of being meticulous on appearance.]
