rear street lynx kit went in easily . Bill was very helpful , car now has a ford 9 inch rear end with 3:75 gears because the owner didn't car if it was all Chrysler , and is a blast to drive. it has the front altercation as well and drives like a go cart i recommend his products for any one who does not mind altering their car in this manner. It is a great improvement over original cars with drum brake/steering box set ups
