T/A leaf Springs

Hi,
Does anyone know what the Arch dimentions are for the rear springs on a T/A?
Thanks,
Jay

I tried to get a figure on this about a year ago and didn't get a response. From what I understand they have 1" more arch than the standard spring so the exhaust will clear. But what is the arch number for a standard spring???

I did a little low tech reaserch on the phone and found out they should be about 7 3/4 to 8" with the "standard" spring being 7".

I'm sure the more people I talk to the more answers I'll get but that one seems the most consistant

I picked up a pair from Firm Feel and they were too low. You would contact the exhaust trumpets just crossing the crown of the road! I had to get them re arched at a local spring shop
