Welcome to the forum. If I might suggest, use the Google Custom Search feature to answer any question you might have. If you can't find the answer we're always here to offer advice.
Specifically what are you having problems with? Engine mounts? The Panama Jack is a cruiser frame with a larger down tube. They often require a special front engine mount. Try looking in the 'Mounting' section for what others have done. Again, try the 'Search' and type in keyword, "Panama Jack" to see what other members have done with their Huffys.
Good luck. Have fun and ride safe.
