Let's be sure we have this right. You have a Chevy truck (year?) in which you have installed a 235 and a SM465 tranny from a 69. I'm assuming your truck is a 3/4 ton. If your driveshaft will work, except for being too long, I would recommend you find a local driveshaft shop and have them cut, weld and balance your shaft.
