All,
I have just begun to install the three point seat belts made by Beams Industries in Oklahoma and purchased from SS. The forum Search function found this thread on installing three point belts and I have read it a couple of times. My 1965 Series IV Alpine has lap belts, and I plan to use the holes in the floor for the floor mounted connections of the Beams belts. Though this thread does have lots of good information, I do have a couple of questions as follows:
Bill Blue - On my Series IV, the reinforcing plates are exactly where you stated they would be- thank you. There appears to be a Phillips head screw head on the wheel side and it is screwed into the nut that is welded to the plate .The undercoating makes it a bit fuzzy and will have to be scraped off before removing the screw.
I can feel the tip of the screw when pressing hard on the interior naugahyde at the point your measurements indicated, so I presume the thing to do is remove the screw, cut a hole in the naugahyde for the screw to fit into the nut, and use the screw to fasten on the upper (non-floor mounted) end of the 3 point belt.
Please comment when you have time.
Wombat - As I read your post, you broke the factory belt retainer screw/bolt when removing it from the nut on the retainer plate and I wish to avoid doing that. Considering the age of the car, possibly some WD40 sprayed on the interior and wheel well parts of the screw will help. Do you have any other suggestions?
Toyanvil - beautiful interior and belt and roll bar job. Just what my son wants me to do, but I got along for years with factory three points on my 1963 Alpine and so I will go with that first (there are several other things I need to get done before worrying about a roll bar).
Alpine II - thanks for the information on the Securon belts - I found their web site and bookmarked it for later reference.
Dave - thanks for starting this thread as it was just what I needed to read before installing my 3 point belts.
