I am helping a guy put together a front end on a 68 camaro. Does the pitman arm length have to be the same as the idler arm length?He wants to use the stock 5.25 inch idler and step up to a 5.8 inch pitman to get a quicker ratio steering. Will it work as I see Ricks first gen only sells one idler arm but he has 2 different size pitman arms.
