The Caddy has the BPO bolt pattern. I have the 200 4 r behind my 500 Caddy. Lower first gear and has OD. These can be beefed up they were in the Buick GN
I used to watch it quite a bit, but lost intrest in it, a couple of years ago.
Does anyone watch Shark Tank? It is pretty interesting, and always different.
I have a 600 and we just out grew it as far productivity was concerned. It will only cut 3/8 at 15" per minute. Then it would overheat in about 25 minutes of continued use. We bought the new Hypertherm 85 and it is a real work horse for us. It cuts the 3/8 at 75" per minute and runs nonstop...
The seller will have their warranty posted and there return policy. It is still within that time frame.
I sell a lot on eBay, and don't have much problem at all.
I am not exactly sure what you are using, but I have been buying these for a long time, and they work great. I buy them 100 at a time.

Probably be OK, we build all of our front radius rods 27" but we custom build a lot of other lengths also. The shortest one so far were 15" long, for a customer, and we have done quite a few at 24".
