How long should they be?
Thanks
John

Much easier to get them out!! | | | | | Joined: Sep 2006 Posts: 2,393 Shop Shark | | Shop Shark Joined: Sep 2006 Posts: 2,393 | Someone(maybe you Tim) some time ago mentioned about using the cut off bolt to steady the trans when removing. It really worked well me more then once too. I did decide to use 6" bolts though.

Shop Manuals all state that "guide pins" should be used when installing a transmission. It took me many years (and many transmission removals/installs) before I decided to make my own "guide pins" (now I don't waste any swear words when installing an SM420). | | | | | Joined: Jun 2009 Posts: 235 'Bolter | | 'Bolter Joined: Jun 2009 Posts: 235 | I've got a 4 speed on my '53 3/4 ton. I got two 6" carriage bolts like someone on this site told me not two weeks ago. On the left side there was enough clearance to use the whole bolt. On the Right side though I had to cut the carriage bolt only about an inch longer than the bolt (screw cap) that came out because part of the transmission protrudes out far enough behind the hole to block anything longer. This was enough though as I only screwed the carriage bolt in four threads. The longer left side gave me the stability I needed after I ran out of bolt on the right side (of course, I was removing). Good luck.
