Tim, the engine towers/mounts from the 232 will bolt right to the 4.0L. Mount bosses are the same on both engines as you suspected. One of the bolt holes on the left side may be bigger and drilled/tapped to a metric size. That was for the knock sensor on 87-90 models (is on many 90s blocks so they could be used for replacements... or AMC/Chrysler just didn't change it). If you need that hole just drill the tower and get the bolt that fits. You can't use an A-500 trans though. The 4.0L uses the AMC/Jeep late model V-8/six bolt pattern. You can use the AW4 out of a Jeep but either have to get a 87-2000 trans controller (from a Cherokee, not Grand Cherokee) or make a manual shift box. The manual box is only convenient if you have a console with arm rest and can mount it where your hand will naturally fall on the shift knob (simple rotary switch -- di ----------------- ----- Original Message ----- From: Timbuckner428@xxxxxxxxx Hi Eddie, so.. what id like to do is put a 2004 4.0L ( 242 cu in) Jeep in a 68 Scout 800... I am using the a-500 auto trans so trans bolt patterns are no issue here... My question is this... The 69 ?71 scout 800?s came with the amc 232 ... I am told that the 4.0 is part of the same engine family... Are the motor mount Bosses the same on the 232/ 258 and the 4.0 (242)?...I am thinking if I get the right engine towers and the right mounts that this will be a direct fit.... Thanks in advance.
