[HELP] I want to make CWM recovery for LG p714

Hi im trying to make a CWM recovery for the LG P714,i made a rom dump using this thread:

http://forum.xda-developers.com/show....php?t=1771347

but i only got this files:

checksum.md5
config.gz
system.info.gz
system.tar

i was reading and i found this website to make CWM recovery: http://builder.clockworkmod.com/

i need my image file,but i dont have it,i also read that i need to convert system.tar to image.img,but i dont know how to do that,does anyone can point me into the right direction please,in order to get a CWM for this device.

btw im using Win 8 x64
