03 Cobra pulley arrangment ?

[Whippedmach]

Im currently putting together a eaton conversion on my 04 mach1 i have allmost everything neccessary. My question is as far as the lower pulley/harmonic balancer. Can i just purchase a lower pulley kit from LFP or will i need to do this plus the factory balancer. Also i wanted to run a 4lb lower and a 2.92 upper does anyone know a good place to purchase these from at a good price. IF any one has the balancer assymbly or the two idler with funky bracket thing let me know. I have the timing cover i just need all the pulleys and brackets that bolt to it and i'm ready to build the car. Promotion 6spd-forged shortblock,ported heads and intake. all necessary fuel and cooling upgrades

You will still need the factory harmonic balancer. I did this same conversion last year
