I'm trying to maintain an oem height and deal with insanely bad Tulsa roads, so what should I set the adjustments to? the rears have to be adjusted off-car so I'm hoping to set them correctly from the get-go.

 

For the rear full soft, up front you'll need to verify how many total sweep of adjustment you have. I've got 9-1/2 sweep total on my front Koni SA's, you might have more or less.
I've got a 625lb.in. spring rate and have mine set to 5-1/2 sweeps from full soft, so I'm going to roughly say 2-3 sweeps, probably 4 at max., since you've got stock springs with a 292 lb.in. spring rate.

 

Do you have a stock rear end, 12 bolt, 9" or D-60?

Go up one click with a 9" or D-60.

 

stock rear, i'm putting stock springs back on, and I forgot to mention its a convertible with a 150 lb heavier iron block
