Does anyone know the crop numbers for 2.35 matte so I don't
have to calculate them?

Teach a man to fish...

In HD (1920 x 1080):
1920 / 2.35 = 817 (so 1920 x 817 is a 2.35:1 canvas)
1080 - 817 = 263
263 / 2 = 131.5 (so crop 131 or 132 off the top and bottom)

In SD (720 x 486 NTSC, .9 pixel aspect):
720 / 2.35 = 306 (but this assumes square pixels)
Correct for .9 pixel aspect:  306 * .9 = 275
275 / 2 = 137.5 (so crop 137 or 138 off the top and bottom)

I'm rounding here and there but what's 1 or 2 pixels amongst friends?  :)
