The only difference on the Lotus racks from the Herald/Spitfire one are the tie rod length/threaded portion and the rack limiting stops.

The Elan tie rod is 7.59 inches (ball centre to thread end) versus 8.715 inches on the Herald/Spitfire but they cannot usually be altered as the rolled threads mean the diameter where the Lotus needs the thread is already sized to about the thread minor diameter.

The rack limiting stops (you can usually reuse both) are sized as follows:
Pinion end: 27/32"id 1 1/16 "od 9/32 " long spacer welded to the locknut
Outer end: A spacer 27/32 " id 1 1/16 " od 1 3/4 " long
