I had an earlier post on a 68 GTX I went to look at and I now have a copy of the build sheet but I'm having trouble understanding it. For example the box that says "trans" has "541" in it but I don't see a match on the some of the decoder sites I'm looking at. Can anyone point in the right direction to decode? I was going to post a picture of the build sheet but I'm getting an error message that file can't be larger than 2MB so not sure if there is a way around that.

On a side note I'm going back to take another look at this car as the first time I looked I didn't have much time and was in a hurry but the car would still be a full resto with all the sheet metal that would need to be replaced.

Thanks
