    Installing Newer sponsons on my 10 TX.

    Guys I am gonna install the newer style sponsons on my 10 T-X..
    I noticed that the Sqaure bolt for the backing plate is $8.99. I believe I am seeing this correctl;y and thats like $90 bucks just for them alone. Anyone see any issue with useing regular stainless bolts, waskers and a nylock nut?

    Or am I just reading the price wrong and it is $8.99 for all of them?

    They really are pretty expensive. Unless you drill new holes the new sponsons won't fit. The Riva sponsons for previous years will fit no problem though http://www.4-tecperformance.com/inde...roducts_id=303

    I have not looked, so if this is a crazy simple question forgive me. BUT why do I need to drill new holes? The back plate placement?

    Yes, that was the plan. I was hopeing the backing plate was bolted to were the old sponsons bolted and ofcoarse the blades bolt to the backing plate.

    2010-2011s have different hole pattern for the sponsons. the backing plate won't just bolt up. The only alternative is a costly retrofit of the 2012+ or getting the Riva ones

    Yep I have done it , I did have to drill new holes but it was worth it

    Don't buy all the bolts , buy one of each and go to a bolt bar and buy them , $8.99 a bolt

    Here's mine
