Wondering if anyone knows the knuckle to knuckle length of a capri steering rack, thanks.

700mm according to rodsnsods.

NB Capri racks have 1/2" unf threads

700 mm would be spot on, I'm doing a spaceframe capri. Was going to use sierra but found out that rack has to be in line with wishbone pivots so it's too wide. Cheers for getting back to me.
