KZ750G intake boots

Hello. I’ve just discovered that my 1980 KZ750G carburetor intake boots have developed cracks and I’m trying to find reliable replacements.  I found some on the JBM Industries website that should fit, but I’m not sure. Has anyone used these and which should I buy that fit? Or is there another source option?.   jbmindustries.com/carb_sockets.html  

jbmindustries.com/carb_sockets.html I’ll take that as a “no”.   

this is what I me looking at… angles or not angled. 

I’d rather not buy some used ones off of eBay. 

But you can go on eBay and search for the OEM part number - 16065-036 (from Partzilla) - and see which JBM items look like the originals. CMSNL had a good picture, too:

 

They look like the straight ones to me. Thanks man.
