How much turning DC.8-62 into 8-72?

[Cornishman]

Can anyone tell roughly what it will cost once the option becomes available  to re-engine DC.8-61/2/3 to upgrade them to -71/2/3 ?  Also roughly how long does the refit take and does it automatically count as a D-check?

Thanks for any advice

The cost is roughly the same as a d-check - and takes 20 more days (so 100 instead of 80) as I recall

And yes it also includes a D check
