Rack and pinion steering in a 120

I have a standard 120 ots with its stock steering box, and a 120 fhc which came with a well executed rack conversion. They feel very different on twisty roads, but what I don´t get is why my 140s (with their rack and pinion boxes) feel so different to the 120 with the rack conversion…?

Hi peder, I have been looking in vain for someone with an XK120 rack steering system so I can evaluate whether or not To try and do it to my FHC. All I get are arguments against it. That may be what I decide, but without cogent and accurate info I have no way to decide.

If you are willing, I would love to get pictures and measurements of your system.

Since this seems to appeal to almost nobody, perhaps you can send whatever you care to to my email - alphajag@att.net

I look forward to hearing from you as the lone person who has any avowed knowledge of this.

Best regards, Brian

Peder the difference in feel might be that the 120 FHC rack is mounted direct to the chassis,
and the 140 rack has standard rubber mounts.
