Baldur

I want to replace all the structs and springs on my 91 LS400 (now @ 150K miles). What later year models will physically fit? I want to use 94 or later because they have a stiffer ride.

I was told three years ago the cost would be about $ 360; the receiving unit must also be changed. I have been able to track down the necessary wires connected to the recieving unit that lock & unlock the doors. I am working on adding an aftermarket unit that will also unlock the trunk as well for a cost of $ 50. All the wires are in the trunk and not that hard to get to.

Yes, this is what I mean, My keys have finally quit even with new batteries. I want a low cost way to lock/ unlock using an aftermarket device. Where should it be installed and how to wire it into the present system (91 LS 400)

Is is pratical to replace the present keyless control unit with an aftermarket unit that will wire in place. If so, what is recommended and is there a wiring diag available?
