hi there i have a 62 short step as well and am in the process of putting a small block motor in. if you happen to have a v8/auto combo Patriot exhaust products has what they call "Clipster" headers, they are a mid length header to avoid ground clearance problems. They have an online catolog at Pertronix.com i believe. any how, i do not own a set yet but i believe i will try them out. they say in their catolog they will fit but i don't know anyone who has tried them. just thought this could solve your problem. if i end up with them i'll post if they do indeed fit well. the part number they list is H8021 they claim it fits 1/2 and 3/4 tons from 55-65. jegs and summit both sell this header. there is pictures of them on there
hope this is of some help,
Scott
