Width seems about right. There’s one for sale locally for fairly good price.
Is the lug pattern right for original wheels? Could a guy make the parking brake work with the original pedal and truck linkage?

The first Colorado's had drum brakes which made E-brake hookup easier. Since axle flanges need re-drilled anyway we now use Explorer rears with the rotor also being the brake drum and a conventional E-brake layout. The Explorer width is 59" vs 61" for the AD so STEEL spacer or wheel with correct offset is needed. The aluminum spacers need re-torqued periodically. Both have ratios from the 2's to the 4's available with 3.73 being the most common and is the automatic overdrive unit.

What year explorer rear do you use?

I understand the wheel base numbers are different than the ADs, but I wondered about how close the front suspesion might be to an AD.
Thanks. | | | | | Joined: Oct 2020 Posts: 43 'Bolter | | 'Bolter Joined: Oct 2020 Posts: 43 | What I mean is, it's got to be some kind of a full frame, but does the mounting from the front suspension onto the colorado frame
look like something that could be cut out as a unit and grafted into a different frame? Has anyone heard of this being used? | | | | | Joined: Sep 2011 Posts: 1,459 'Bolter | | 'Bolter Joined: Sep 2011 Posts: 1,459 |
