1967 c10 LWab Inline 6 /s peed to LS/4l60e driveshaft length

Ok..I have read tons of posts that said LS swapping in with a L60E you can use the stock driveshaft as is. I can't see it. I yanked out the inline 6 and 3 speed manual. I got the LS (LR4 4.8L) mounted on 73 V8 mounts with setback adapter plates on the LS. I have the engine as far forward as ai can (oil pan is only 1/2" from cross emember) and my driveshaft is about 3 inches too long. I was going to get it cut. Before I did that wanted to make sure I wasn't doing anything way off.
