Default Seat belt tensioner (early vs late)

Hi again yall,

Trying to swap late model vaders into my early model car. Obviously one of the tricks is to swap the tensioners but I am having the following issues:

Later style tensioners into sport seats (previously had early style tensioners) - there is play when mounting the later style tensioner into the seat rail; cannot bolt all the way down against rail.

Early style tensioners into vaders (previously had later style tensioners) - early stule tensioner does not sit flush against the rail

Were there differences between the seat rails in the years?

Seatframes of <95 and <95 are totally different. Although don't know if the actual rail part where the tensioner is, is different.

I once swapped later style pyro tensioners over to a seat with mechanical ones, but it was the same base frame. You need the bolts itself as well, as they are different.

This actually sounds like my situation (the frames between my two set are the same, it just appears that the tensioner and mounting thereof is different).

Which bolts are you referring to? If its the one for mounting the tensioner onto, how does one remove it? seems like its impossible without going further and disassembling the rail when I last looked at it

Uh, the bolt is right there at the base. Don't understand you can't get to it.

When I swapped mine. One mounting bolt, one locating bolt.

Curious, do you happen to know how mechanical tensioners work? The bentley manual calls for disarming it by turning the dial before removing it. Any reason to do so?

Yes that blocks the little ball (I believe) from being able to be bumped away (like in a crash), which holds back the preloaded spring, that attaches to the belt buckle.

Pain in the ass to remove with electric frames because it has to be done in the car and you have to be very strategic.

1) remove seat bolts mounting them to the car and remove headrest for wiggle riom

2) raise the seat bottom to the highest setting

3) disconnect battery to prevent airbag light fault

4) unplug electrical under the seat now and move the seat around so that you can start unbolting the seat belt tensioner (if mechanical tensioner disarm it first)

5) that pin is now accessible because the center seat frame would block it at its lowest setting; yank the locking clip behind it with pliers and angle the pin out of the socket
