Block Casting Numbers are found right above the oil pan on the front right side inside a concaved area. That number will help ID what you have...

At the link in my earlier post, you find that XA refers to 3600 (3/4 ton) with no drivetrain options. | | | | | Joined: Mar 2011 Posts: 85 'Bolter | | 'Bolter Joined: Mar 2011 Posts: 85 | Thanks I missed that in your post. Maybe I need new glasses! Thanks again. Steve | | |
