I have been making these repair panels since 1984. If you have longitudinal rust, door gap problems or excessive body flex, this panel system is a proven fix. I also have sold many to install in track cars and big engine swaps.
This system is the fastest, easiest and least expensive way to solve your chassis problem. Does not require removal of body panels to install. MIG or stick installation.The panel ties into the 3 bolts of the trailing arm mount and extends to the front wheel house if necessary.Excellent instructions included. This system has been used with Engman's/ Maddog's Porsche 914 Inner Longitudinal Stiffening Kit $375. Includes stateside shipping! 914 Limited Brad Mayeur 1162 N.

These require removing the existing jack points, and the sill support triangles. Then these slip up under the sills to support them.
I'm installing these on my car now. I had some rust around the jack points, so they had to come off anyway. I'm using pieces from restoration design outer longs to patch the area around the jack point that needed to be cut out, then adding Brad's panels over the top. The car will definitely be stiffer and ready for another 50 years:) If your longs and jack points are rust free, then it makes more sense to do the engman/maddog interior reinforcement. If you haven't taken your rockers off and checked thoroughly, do that before you decide. cheers, dug |

The RD outside stiffeners are way easier to install, IMO. However, the increase in metal thickness at the door seam makes it a little awkward [later] when installing the inner door seals. Overall, I think the maddog kit provides better support and is worth the extra effort. |
