Has anyone seen any AM parts to correct the Academy Sheridan? Anyone know about any AM manufacturers planning corrections? I was hoping that by now there would be a slew of upgrades, but I've only seen a handful of add-ons.

AEF Designs has a couple correction/upgrade sets for it. One for a Vietnam era M551and one for a Just Cause/ODS era M551A1 TTS, they also have a gear set.

Legends Productions has a gear set for it.

Fruil (I think) just released a new track set out for it too.

If you're talking about the grossly incorrect angle on the TC cupola, I'm still looking for my mold which corrects it.
Anyway, it would be in clear resin. I may mold a corrected driver's hatch area,but it's not on my "to do" list soon, as I already faught a battle with this thing several months back. I generally make a mold if I have to do at least a few of the same thing.

Thanks guys, but I was hoping for something that would correct a number of things; TC cupola, idler mounts, a number of things, but especially the driver's rotating hatch - I think that is the most glaring problem, at least for me.
I may have to look at grafting one from the old Tamiya, it has a host of problems also, but maybe between the two of them, I can get closer to "right".
Then again, judging by some of the pics I've seen, I might be able to build it OOB and just cover the thing with supplies, fencing, tents, MRE's, boxes, etc., etc...

To be honest, that's what I did, but still had to detail it. It's closer than the Academy one. Didn't feel like fooling with the RTV at the time so no mold of it yet.
