Recently bought a roundtail and wanted to install three point belts. I think that this is the single biggest safety installation that can be done. Available belts are, frankly, ugly. I just wanted to show off how I integrated the sweet lap belt system of the roundtail cars with a three point system:
1. I bought three point belts for "alfa romeo spider" from ebay carpartswholoesale. The belts come as a pair for $79.
2. I detached the stitching at the lower (lap belt) anchor point.
3. I removed the anchor, removed the buckle, and removed the b pillar anchor (useless on a spider!).
4. I inserted my original lap belt buckle.
5. Replaced the lower anchor and had See's Automotive sew it back on.
6. drilled hole in the usual spot (comes out the inside of the rear wheel well as other have shown), primered, and bolted the shoulder belt reel into place.
7. placed a vinyl strap around the outer headrest bar through which I passed the shoulder belt.
8. secured the lower anchor in the usual lap belt anchor position.
I'm pretty proud of this, so please, hardcore alfisti among you, go easy on the change from original. The belts really seam to work great, and I think that they will offer some additional protection in a head on collision, as the stress is really at the rear anchor, not at the seat.
I'm going to attach some pics. Tell me what you guys think.
