Thanks for the info. I've been in contact with E-tec. The fellow I spoke to said they were aluminum and the round needs 3/4 id pipe. This may not work for me since my fabricator already bought the 7/8 od tubing. I'll talk to him to see what can be done. If he can easily use the 7/8 on other stuff, I'll probably go with e-tec parts.
