Old Bolt Method - Mixed Lengths on Flange Set

It has been a while since I have run across this situation so if someone could review this methodology before I commit the labor to it, I would appreciate it very much.

I have a flange where 2 bolts are passing through a flange support (ATTA).  The way I am going to approach this is as follows:

[LIST=1]
Create an SBOL, with 2 bolts missing
Make a SPRE for this particular FLAN
Reference the SBOL in the SPRE
Add an EXTRA for the SPRE with the 2 bolts
Reselect the FLAN in DESIGN from the old SPRE to the new SPRE
[/LIST]
Does this approach sound correct?

If it helps, here is a picture of this configuration.

If this is a isolated case, I think it´s ok in my point of view.

Thanks.  Getting bolts to come out right is a real challenge, but if you do the right things the right way then it helps.  As I thought through it, this seemed like the approach that would work.  Now I need to see if the theory matches the reality.
