65 Mustang Fastback Suspension

[bighead]

Hi,
I am trying to upgrade my 65 Fastback suspension for leaf spring to coil over. There are a few different options out there and I was wondering if anyone wanted to chime in and give me there $.02. I would like to finish building up the car and use it for autocross. I have attached a couple of links of what I am looking for.

Thanks
