R Steele Posted February 16, 2013 Share Posted February 16, 2013 Hi guys, The Mack museum said that I needed to give them my chassis number to get the original paper work for my 1978 mack. Is it diff than my vin number and where would I find it? I see there is a number stamped into the cab when I open the drivers door. Do you fax the museum the info?

2stacksuperdog Posted February 16, 2013 Share Posted February 16, 2013 There is a tag on the door with the model and vin#. The vin is also stamped in the frame above the front axle.

2stacksuperdog Posted February 16, 2013 Share Posted February 16, 2013 Thanks, so it is the vin number that is on the plate inside the drivers door?should be it, check with number on frame just in case, you never know maybe they changed the cab Quote Matt Link to comment https://www.bigmacktrucks.com/topic/29975-where-is-the-chassis-number-located/#findComment-164913 Share on other sites More sharing options...
farmer52 Posted February 16, 2013 Share Posted February 16, 2013 The number stamped in the cab is the cab number. VIN is likely 17 digits (numbers and letters)Per 2stack... The VIN should be on a plate on the driver's door along with the model number. Also check the frame in case the cab was changed.

David Posted February 16, 2013 Share Posted February 16, 2013 A '78 won't have a 17 digit. Should be something like R686ST12345. Quote Link to comment https://www.bigmacktrucks.com/topic/29975-where-is-the-chassis-number-located/#findComment-164933 Share on other sites More sharing options...

Superdog Posted February 16, 2013 Share Posted February 16, 2013 Ken, I think it was 1980.Dad's 1980 Cruiseliner had a real VIN,WS786LST51059,my '81 R model has a 17 digit one so somewhere in between the '80 and '81 model years Quote Link to comment https://www.bigmacktrucks.com/topic/29975-where-is-the-chassis-number-located/#findComment-164993 Share on other sites More sharing options...
607t1173 Posted February 17, 2013 Share Posted February 17, 2013 All vehicles 81 and above are 17 digit . If you want to know what year a vehicle is, count the digits right to left and the 8th will be the model year starting with B-81 C-82 D-83 E-84 F-85 G-86 H-87 J-88 K-89 and so on, the letters I,O,Q,U and Z are omitted so as not to be confused for #'s letters were used thru 2000 which was a Y In 01 they started using numerals starting with the #1. I just looked at the title to my wifes 2012 CTS and it was a-C- so they must have started using letters again in 2011Years ago dealers would sell you a truck manufactured in the previous year but it would be titled as the year it was sold. It was a very common practice, I used to have a B-61 titled as a 1967 and we all know that wasn't correct.
