Question about old 50mm SMC A 1.7

I just snagged one off ebay tonight, but it doesn't come with caps... I didn't care I just felt like winning an auction!

Anyone know off the top of their head what sizes I need (for front and back) and where I can get them for a good deal??

I appreciate the input!

(This is my first lens purchase btw, so I'm pretty excited)

You need 49 mm for the front cap.
Good photo shops (especially those with 2nd hand stuff) normally have a junk box with used caps.

The back cap is the same for all Pentax lenses.

Thank you very much Blende, I appreciate your help!

I will go and pick a couple of those up tonight so I can protect this thing when it gets here.
