that's a great find on the 2wd arm. i am currently using an 80 series arm which is working well but i like that the 2wd arm is a little shorter with less drop. i just looked up the part on your link, you got the last one i guess(showing 0 in stock).
Yes, it worked out perfect for my application and was cheaper than the SKY arms. Another place I saw one was on Ebay, it was used but it was cheaper.
Too bad it is out of stock now that makes it about the same price as sky's new.
The 80 series arm is a little longer than a stock IFS arm right? So in effect, you gain a faster turn, but it would be slightly more difficult. For some they may run into their steering arms hitting.
