Questions regarding High 15 sheetmetal p/n's versus Little 15 sheetmetal p/n's

I was looking in my parts books tonight trying to resolve some sheetmetal part numbers I needed to order and well I created my questions regarding High 15 sheetmetal p/n's versus Little 15 sheetmetal p/n's.

I See that the fender p/ns for a little 15 are T708/709

On a HC 15 the fender p/ns are 1B4937/4938. Are these HC15 fenders the same p/n the same as a High Ten?

I also see that on a Little 15 the lower engine side panels are p/n's 1B3447/3448 but on a HC15 the lower engine side panels are p/n's 1B4935/4936

Last I show the seatbox on a High 15 to have completely differnet part numbers than a Little 15 and a ten seatbox.

Anybody able to clarify? Cat Iron, you have rebuilt two or three HC15's and possible had new metal made, what did you find?

Guidance would be apprecaited.

Thanks Bob for the clarification. The lower Engine panels are ten also???? OK.

I think this is a keep long term as there are some unique elements to the tractor.

Been a long time since I've been on here...to many other irons in the fire but from my understanding there is one being built real close to home?????? Bob do you have another sweet fifteen you are building?😆 Or is there two being built??? hummm.. 👍👍 The Brothers..
