Sounds like for 6 cyl. engine D-17 or 19, maybe contact Don from Mo. he will probably know. Could be gas or diesel kit, but he would probably be interested. Leon

If they are 3 7/16 bore they are WD45 diesel, the D17 and D19s are 3 9/16.

Most problems can be solved with the proper application of high explosives.
