Mike,
It must be an ABC piston, sleeve set
The OD of the sleeve is 1.102
lenght of the sleeve is 1.760
Top of sleeve to top of Exhaust port .782
Bottem of Exhaust port to top of Exhaust port .250
Sleeve flange thickness .085 (Larger diameter on top of sleeve)
If what you have matches these dimension I think it will work.
If you could maybe you could send me some pics.
