I built a Wedico Peterbilt about 8 years ago and have been away from the hobby since. I built my truck with the Professional chassis using metal axles.
Since joining the forum I noticed you can buy a walking beam suspension from PMD, has anyone fitted one of these kits to their trucks ? also if you have do you have to drill any holes in the chassis ?
The other question is does anyone make airbags which could be used with the walking beam suspension ?
Regards Cushman.
