I don't think there is a 'bigger size' of u-bolts. The difference (I believe) is with the strap/bolt you can't put a u-bolt through the yoke because it's drilled for the bolt. Hopefully the 12-bolt rear end will have the straps/bolts necessary. Currie Enterprises, http://www.currieenterprises.com <http://www.currieenterprises.com/> , lists "U-JOINT STRAP KIT FOR 1310 YOKE" at $6.95, part #CE-4058. The picture shown is u-bolts but it's a "sample image only". I think Year One also has them for $10.60, part #MG328 and are listed as "Type-1 U-joint strap kit. Universal joint strap kits for models using Type-1 universal joints at the rear axle. Includes straps and hardened bolts."
Or maybe someone has a pair lying around from an old project, :*) Dale McIntosh <http://www.chevellecd.com> 1966/67 Chevelle Reference CDs ACES #1709/TC GOLD #92 <http://www.chevellecd.com> _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jim Sullivan Sent: Monday, March 05, 2007 3:01 PM To: The Chevelle Mailing List Subject: Re: [Chevelle-list] 12 Bolt yoke All this U bolt/ Straps information makes me think about my situation. My '69 Malibu 307 had a 3 speed on the floor with a 10 bolt open rear. It has the U bolt. It's going back together as a 402 with a 4 speed and a 12 bolt posi. Sounds like I'm not going to be able to use the original U bolts. Is that right?? Even if I use U bolts, I'll have to get the bigger size???
