Starting motors are identified by a manufacturer's model number stamped on a metal tag attached to the motor housing, as shown in Fig. Ignition distributors are identified by the manufacturer's model number stamped on a plate attached to the distributor housing, as shown in Fig. Generators are identified by the manufacturer's model number stamped on a metal plate attached to the generator housing, as shown in Fig. (A-8, page 5)Ĭarburetors are identified by the manufacturer's model number stamped or cast into the carburetor body, as shown in Fig. The differential gear ratio may be determined from the axle ratio tag installed under one of the gear cover screw heads. (A-5, page 4)Īll live axles on 'Jeep' vehicles are identified by a model number cast into the axle differential housing near or on one of the reinforcing webs, as shown in Fig. It is on the left side of the vehicle for model CJ-5 as shown in Fig. Sorry I can't narrow it down any further than that.Īll of the able information is assuming the body is mostly original, anything swapped in (like front fenders), will throw off the diagnosis.The vehicle serial number is stamped on a metal plate located at the dash under the hood. If it is a 2 piece design, then it's a '70, if it's a 1 piece, then it's a late '70 or '71. If you do have front fender marker lights, then we know it's a '70-'71 CJ-5, and you need to look at the rear axle.

So, if you have no front marker lights, we can conclude it is a '66-'69 CJ-5. If you have front marker lights on the fenders, they came in '70. If not, it tells us nothing as they were an option. If you have a roll bar and electric oil and amp gauges, they debuted in '69, so we can narrow it down further.

Therefore we can conclude it is a '66-'71 CJ-5. A CJ VIN number helps owners and mechanics identify details regarding the engine type, the place it was built, and more. Also, we know that the first 225 V-6 debuted in '66, and Kaiser ended their era in '70, but the lineup didn't change until '71. In 1923 another 4 cylinder model was introduced, this time designated Model 92, but on a 106 inch wheelbase and more readily remembered as the Bird series. Unfortunately, the records weren't kept the best in those days (60's), so the best I can do is come up with a range of years.īased on the data you have given we know Kaiser didn't put their name on jeeps until '63, before that they kept the Willy's name. During the period 1920 - 1926, Willys Overland produced a succession of 4 cylinder models which were designated 4, 4A, 91 and 91A - all on 100 inch wheelbases.

It's a CJ-5, open body (no top), left hand drive, 4WD, with the 225 V-6 engine.
