Re: Identifying year, etc. by serial number on jeep
It's a CJ-5, open body (no top), left hand drive, 4WD, with the 225 V-6 engine. That's what the 8305017 decodes. After that it's the serial number.
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.
Based 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. 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. Therefore we can conclude it is a '66-'71 CJ-5. If you have a roll bar and electric oil and amp gauges, they debuted in '69, so we can narrow it down further. If not, it tells us nothing as they were an option. If you have front marker lights on the fenders, they came in '70. So, if you have no front marker lights, we can conclude it is a '66-'69 CJ-5. 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. 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.
Sorry I can't narrow it down any further than that.
All of the able information is assuming the body is mostly original, anything swapped in (like front fenders), will throw off the diagnosis.
