Not straight cut, but "apparently" it still gives off a whine (with helical cut).
My 32 box was doing it.
People have asked if it was straight cut.
No, it's not.
For a drive in, drive out service, start making calls and getting prices.
A 26 rebuild will be completely different to a 26/30 build(cost and parts wise).
The 30 has much better driveability.
The 26 is easier to convert back to standard under a defect.
