From LDD part, I measure (for top rim) an internal radius of 32.4 ldu and external radius of 36.1. The major radius is thus (32.4+36.1)/2 = 34.25, and the minor radius is (36.1-32.4)/2 = 1.85. The ratio is thus 1.85/34.25 = 0.054. We are thus looking for tori whose name end in 0540. Since this value is not critical at all, we'll choose an existing approaching torus. I'll go with t01o0625 and t01i0625 (ratio=1/16). These tori must be scaled in all directions by major radius, 34.25. Thus internal diameter will be 34.25(1-1/16)= 32.109375 and external will be 36.390625.

Other values (cones, etc...) needs to be derived from these numbers...

I hope I am reasonably clear...
