Unvented Shower drain length question

I figure now is better than later to know if my plan is flawed.

I am putting in a new shower and the planned drain has about a 48" unvented run to the vented waste using all 2" ABS. Dimensions of the layout will be apprx a 8" drop to the P-trap and a 42" horizontal run to a long turn wye.
If I read the code correctly, 2" is good for a combined 60".
The drain should vent itself for this length, correct?

Am I good with this, or am I missing something?

Thanks for any advice.

If there are above fixtures connecting to the pipe you are tying into you can't do it.

Thanks shacko,

The shower is the furthest upstream on a secondary line (vent). Downstream of the wye is the tub. These are the only 2 fixtures on the run. OK now?
