OK....i think I decided on this T-lok http://www.rpmoutlet.com/musv6fordgear.htm
and these 4.10s http://www.mustangtuning.com/v6gears.html
. Are those both good choices? Now I just need u to help me with the programmer???? And last but definitely not least...what kind of places install these things..I've called dealers and they say they wont. Should I just try performance shops? Thanks again!
