Default LM3875 PCB Footprint

I'm quite new to OrCad (just got a copy today) and am wondering if anyone has made a footprint for the LM3875 or could instruct with suggestions as to where to download such footprints. If I have to just make my own footprint, any suggestions would also be nice. All help would be greatly appreciated. Thanks,

It's quite easy to do this by yourself.

First line of pads
X= -268, -134, 0, 134, 268, Y = 0

Second line

X= -335, -201, -67, 67, 201, 335, Y= -200

Pads, 95, 75, 75, 90 hole 1.1 mm
Compmask, complayer, soldlayer, soldmask

The pads are made for plated through holes

-393,7; -11,85
-393,7; 163,35
393,70; 165,35
393,70; -11,85

All units in MIL.

Just take a look at my gainclone if you want to see how it looks. Download the pdf's.
