Wow! You have a big job ahead of you with this leak. Rob sells the origional equipment made by Garrett which is made in Mexico. Garrett 720706-0002 and Chrysler A 112 500 0000 Are the same intercooler. Rcompart (Rudy) makes a after market version. Either one works well. If your going to keep your car,then purchase Rob's coolant isolation kit. It will seperate the engines coolant from the superchargers coolant. Your new intercooler will last longer this way. The engines coolant is alot hotter than the heated coolant that the supercharger makes. The brittle aluminium of the intercooler doesn't get as hot and expand as much when the coolant is seperated. Rob(NeedsWings) has everything in a packaged deal to do this job. Good Luck....Squirrel Crusher
