Cut your good one in half and braze them together...
If it looks like it'll leak if you use your old one, I'd either make a visit to majestic honda or a local junkyard. I have no idea though, sorry.
Also, I thought the VX just had one (really expensive) O2 sensor. Majestic honda usually posts parts diagrams, so you could figure it out that way...
