Updating old mods to work in 0.6.1..... Can it be done?

I'll just get right to the point; I have an old mod I'd like to add to my game (70's Ford F100), & I've done all I can to make it work, but when I spawn it, it's invisible.... I can still drive it, hear it, etc., I just can't see any parts of it. I managed to get another one working for personal use (86 Silverado), but this one seems to be beyond my scope.... Can anyone possibly help me out here?
I don't know if it's a .jbeam issue, a .cs issue or what it might be. As I said, I've tried everything I could, but my modding knowledge isn't near enough, apparently.
Thanks for any help in advance.

 

Awesome! Thanks for the help. I'll go try that now.

 

Finally got around to checking the console..... Far too many red lines to type out here. Missing meshes etc.
I think this is too much of a project for me.
I can post a screenshot if you want, just let me know

 

Post a screenshot, post a link to the mod, etc.

 

Well, I'm confused.... I reinstalled the mod, & after removing a few other mods I didn't much care for (84 F150 & Bronco), it works now.
I can still post the link & screenshots, although I have to be honest, I'm pretty sure the credits attached to it could be wrong (who created it, etc) & I really don't want to step on any toes here. I also don't want to break any of the rules of the forum.
Perhaps it'd be better to PM the link to interested parties? I'm not sure of the best way to go about it.

 

If other mods were the problem then it's a moot point, I wouldn't worry about it.
