DC8 Conversions pricing

[MikeS]

I know the conversion system is still work in progress so here are two points that could be considered:

When converting for example a DC8-62, all options have the same price tag. Converting to 72F should be a lot more expensive than converting to 62AF due
new engines.

It would also be helpful to be able to know the base price and time for a conversion before purchasing an aircraft. I know it varies according to aircraft condition but some kind of reference price would be nice (a newbie would be completely clueless) .

Thanks
Mike
