tie bar length Formula 1990 292 SR-1 Bravo 1

Measures 34.5" from drive center to drive center, so do I go with a 34" or 35"? Emailed Imco, no response.
Thanks in advance.

They're adjustable.

Thanks Jake. Right, I know they are adjustable, but I'm not sure how they are measured, as in adjustable from short to long or long to short. If there is less than 1/2 inch adjustment, I might have a tie bar for sale after purchasing.

Call NV imco. They know what's up.

Just measured mine, drives 34.5 inches on center. Tie bar is 31 inch not including jam nuts and threaded ends. Not sure if this helps, but that's what mine is.
