Vector Optics Paragon 5x25x56 gen ll

Hi, new member here just starting out, I'm needing some guidance please on the above scope I have.
Vector have now discontinued this scope before I had the chance to buy some flip up lens caps.
Could someone recommend a brand I could get, regarding the internal thread size I have no idea what this for each end and how I would even measure it.
 
Internal threads should only matter with the screw on sunshade, if it came with one. Flip up lens caps are simple push-on products. If you contact Vector they can give you the sizes for front and back. There are plenty of places online to buy lens caps; I can't think of any right now, but I'm sure someone will chime in on that. BTW....I'm a big Vector supporter. I really like their glass quality.
