18 inch spider offsets

[spartridge]

Quick Q - Does anyone know if a set of 18 inch spiders from a Tuscan (ET 33 Rear, ET 42 Front?) have the same offsets as Cerb, Tamora, T350 and Sag spiders? i.e they are interchangeable?

Thanks

Cerbs are 99% of the time fitted with the front Tuscan set. All T cars are the same.

Those are the offsets documented in Graham Varley's Bible for the Sag.
