Sometimes, metric or American sizes can interchange, making the task easier. Here is a table of sizes that interchange pretty closely, and the difference in actual size in thousandths of an inch. The differences with a negative sign indicate that the American size is slightly larger than the closest metric size. The asterisk indicates larger differences in size, where the interchange is not as good, and the smaller size tool may not fit on a bolt intended for the larger size. Using the larger socket or wrench may result in stripping the hex of the bolt or nut if much torque is applied. The 27mm socket is used for both the '98.5-'02 Turbo Diesels' Bosch VP-44 and the '03-up CP3 injection pump shaft nut. The 30mm socket is used for the '94-'98 Bosch P7100 injection pump shaft nut, and the 22mm is for the '89-'93 VE pump nut. The 16, 19, and 24 mm sizes are used by various years' injection lines and injectors.

In June, 2014, we bought a Dodge Dart for a high gas mileage car and it has been excellent. However, my wife has been wanting a vehicle that sits higher, but isn't as big as the Ram, so she can get in and out easier. Meanwhile, my daughter was planning to move to Denver and wanted a vehicle that would be good for commuting to work and for exploring trails in Colorado on weekends. Given the snow in the winters and her other criteria, we looked at four-wheel drive vehicles, including the Jeep Wrangler Unlimited, which of course is the premium off-road vehicle and is excellent in snow. It also retains resale value far better than most vehicles. The question was whether it would be comfortable and driver-friendly in urban commuting situations. After driving one, both she and I were very impressed with the improvements in ergonomics, user friendliness, and capabilities of the new Jeeps. She bought one in the mid-level price range, with limited slip differential, towing package, power windows and power door locks. The max-towing package includes 3.73 differential gearing, which is a good compromise for on- and off-road use. She is very happy with it. My research into Jeep features and options resulted in my purchase of a Wrangler Unlimited Rubicon to fit my interests in a vehicle even more off-road capable than my Ram 3500, while being suitable for my wife as an urban warrior. If you are looking for a vehicle with similar characteristics, check out today's Jeeps. They are very modern in conveniences while retaining not just the legendary Jeep capabilities but also some enhancements over earlier Jeeps in off-road performance.
