Although the diesel variant was used in Volvos, the petrol one was only used in the LT, and to make it more difficult it was not specified as often as its\’ sibling. There were a vast array of gearboxes and differentials which were matched to the engines and customers\’ requirements so it is unlikely that you will find a \’set\’ without purchasing a petrol LT. There are links to the excellent LT-1 Forum WIki in the Buyers Guide, in the left margin. You could look at utilising a petrol engine from a VAG Group car which had variants which also used the D24. https://en.wikipedia.org/wiki/List_of_discontinued_Volkswagen_Group_petrol_engines https://en.wikipedia.org/wiki/List_of_discontinued_Volkswagen_Group_diesel_engines I wish you luck.
