help me convert this all grain to Partial mash?

[dabull25]

I was wondering if anyone could convert this all grain recipe to either a partial mash or extract recipe for a 5.5 gallon batch? I can only boil 4.5 max volume. Thanks!

In general, one pound of two-row equals .6 pound of DME. So, 14.5 pounds of two-row would be good with 8.7 pounds of DME. Since that's a weird amount, using either 8 or 9 pounds would be fine. 8 pound would give you an OG of 1.070ish.

There isn't any reason to do a 90 minute boil- a 60 minute boil is fine. You can do the 90 minute and 60 minute hops additions then.

You could mash the grains as given/directed, and then add the bulk of the DME at the end of the boil.

Would the hop quantities be different since I am doing a smaller batch?

Well, if you're making 5.5 gallons instead of 6 gallons, I can't really see it making much difference. You could cut down everything (including the grains) by that amount (.083%), but it sure seems like more work than it'd be worth for 1/2 gallon.
