Hey Larry,
You are ahead of me, I looked at taking a chance and placing an order for one of each too and it came up $48 shipping. The upside if they fit is that I placed multiples of each on in the cart and the shipping didn't change, so you can spread the cost, but I wasn't willing to buy multiples without verifying fit! I've been there, done that and have parts on the shelf to prove it!
The lock also appears to be available on eBay from a Ukrainian seller $10.99 with same again for shipping. The latch he has is different with a metal insert and not cast, but might equally functionally work for $3.75 and $7.99 shipping.
