27mm effective rate hollow bars (actual measure 28.5mm) Sway-a-way/Weltmiester. $200 plus shipping. (Pelican sells these for $344).

These are the perfect T bar when matted with 22mm fronts for a short wheel based car 65-68 and the 69-73 that is driven in a spirited manner. (Street and track duty)

They are also a very good fit for the heavier 74-86 911 for a street set-up.

Hollow bars, less weight in the back, hmmmmm it's a good thing.

These are the size rear bars that are on my 1965 911 when it set a class record at BIR. (that record held for years).
