I know Jag Series 1 and 2 are what was used in most Contemporary's, I don't know what the difference is with the 12 cylinder cars. I don't understand what damping you are referring to, you should have Borgeson u-joints on the steering shaft and solid mounted at the column. Rack and pinion gears don't tolerate shock well, that's why Jag used rubber as do late model Ford Mustangs. How much force do you think it takes to deflect the stock mounts by 1/16" and do you think that is critical to your car's handling or tracking? My kit came with a set of solid mounts that someone fabricated. I plan on taking the off before I complete the car.
