I have notice the bolts need to be longer when you swap from auto to manual.
I wanted to know what size to get?
thread size and bolt size

Well, im gonna assume you mean the trans bolts. and yes they are different because i have done the swap before.
But I cant help you with the sizing since even stock they are all different lengths.
i would say go to a scrap yard and take them from there. or find someone who has extra laying around.
