Look at the diagram for your model. It will tell you a lot of what you need to know....the online shop manuals may have a good pic but not sure of that. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 |
Mo,
Post a few photos of the frame, showing the holes. If you can annotate the holes with numbers, maybe people would be able to tell you what holes are used on a standard pickup.
State the year, size, and model truck.
| | | | | Joined: Mar 2011 Posts: 229 Shop Shark | | Shop Shark Joined: Mar 2011 Posts: 229 | ive got the assembly manual, theres a picture of the frame with all the holes and measurements but they dont state what there for. actually blew it up and laminated it so it wont get ruined working in the shop(cost 3.00). also looked through every page in the assembly manual and cant find these holes other than cutaway pictures. i know the front bed mount holes but i need the back two mount holes on each side. then there is a strut rod that supports the rear fender someplace behind the wheel. so these 6 holes are the ones i need locations for. if anybody could look on their truck and let me know that would be great. thanks in advance
