Anyone here ever installed/seen someone install a Schroth harness in their 240sx

[f s t caz]

knowing the stock automatic seatbelts suck in my s13, and seeing that i could get a right side autocontrol harness for teh cheap ($50), i picked myself up a Mint green autocontrol from HMS Motorsport because their webpage said the harness could be used in any car fitting the seat requirements. Read thru the manual though and Schroth is more specific, stating that it should not be used in any vehicle not listed within the reference pages. Come to find out, the 240's not in there, but from the looks of it, the latest model car listed on the page is a 93. Perhaps they've done testing since then and I just didn't get an updated reference page (no, they don't have the Vehicle reference sheet on their page) or maybe some said oh well and installed it on their 240 anyways. The harness does look really good, and I'd really like to use it, but I'd rather not pioneer my way to certain doom. And I have already sent an email to HMS asking about it, but figured I'd ask here too.

here's a picture just because

yeah one of my friends has schroth 3 point harnesses in his 240 and they go in easy like any other to where the lower seatbelts bolt in and he uses a mountain climbing clip to hold it in in the back.
