elie boone Posted August 6, 2020 Share Posted August 6, 2020 The 5 speed support sits a bit further in the chassis tunnel easily fixed with an additional plate from the original mounting. By gear change extension you mean a raised pivot point ?New clutch assemblyAngle driveSpeedo cabletunnel top coverPropshaft Link to comment Share on other sites More sharing options...
auyt Posted August 6, 2020 Author Share Posted August 6, 2020 Good insight.I do have a a compatible clutch.This car is an Australian delivered Kit with a 4 speed Escort box ( sadly not a rocket box) and has a specially designed extension change which is listed in the manual.A Tunnel Top cover?

Iamscotticus Posted October 16, 2020 Share Posted October 16, 2020 A cover for the new shifter location, as you most likely will not use the old 4spd shifter extension linkage. The knob position will likely be just under the cluster panel tube. Annoying, for sure, but workable.How have you gotten along with that conversion? I need the clutch pressure plate part number.

auyt Posted October 17, 2020 Author Share Posted October 17, 2020 I havnt actually done the conversion, But I do have the necessry conversion parts, Gear change extension, the alloy top cover and a competition shifter, the other things are the shortened tail shaft, and the Angle drive for th speedo.I wasnt aware there was a need for a differnt pressure plate? I though it was the same as the one fitted to my engine which is a Lotus Twin Cam Link to comment Share on other sites More sharing options...
Iamscotticus Posted October 19, 2020 Share Posted October 19, 2020 Auyt, you may want to look into the differences in clutch cover "fingers" as the curved face T-9 release bearing, prefers "straight fingers".I don't know if the supplied cover has those fingers. https://lotuselan.net/forums/viewtopic.php?f=37&t=26074&start=http://www.enfostuff.com/forum2/viewtopic.php?t=223Perhaps someone more fluent will pop up.. Either way, an email to the men at RedLine components would know. Link to comment Share on other sites More sharing options...
