8.75 posi for 68-74 mopar

Greyhound bus is probably the cheapest. 100 lb max on any package. I've shipped large heavy items many times and it's much cheaper. You just need to do is find a bus terminal close to buyer. Also you can get an estimate online at Greyhound.com. All you need is the weight and the length of the package...that's all you need. So get the longest side of the box and the weight and you can get an estimate. I also get the buyers city and find a terminal within 45 miles or so. If they really want it they'll drive 45 minutes no problem!!! If you're going this route let me know and I'll help you.
Hope this helps...
