You might not even need dropped spindles. Could you answer some questions as best you can and I think I can help.
What is the distance from the top of the front tire wheel well lip to the ground right now on your car?
What size tires are you running on your car?
Do you have headers?
How low do you want to drop your car?
How low do you want the k-member to be off the ground?
What size T-bars are you running?
I have run my Barracuda low enough the K-member would smack a parking lot curb strip. But the car had 23.7 Diameter tires on it then.
