I found the Academy USMC M60A1 Patton Rise/Passive with M9 dozer, and upon opening the box I found a hastily assembled hull and turret and a set of AFV Club track.
I remember exactly when I bought this kit - it was 102 years ago and I was staying in a hotel after starting a new job.
I wanted a kit for those solitary nights but the project bogged down very quickly when I saw the huge motorisation holes - particularly around the drive sprocket mountings ... this kit would need more than a hobby knife and some glue, and later research revealed it needed some plumbing for the dozer blade, which was the main reason I was attracted to the kit!
I think a few years later I tossed the AFV Club track in to the box after I found it at a swap meet.
I don't know anything about the accuracy merits of the kit, and I really don't care - it looks like an M60, the tracks seemed to be its biggest shortcoming and it will look cool with all that reactive armour and the blade.
I found a great reference snap in this very site from Treadhead12 (yep, them front hull blocks will also need some re-fitting):

I picked up where I left off by blanking the holes from the inside with some card (I also removed the port side rear bin for the hydraulics box, which left another hole that needed filling):

Once the glue had set, I set to work with putty and milliput:

A dab of Mr Surfacer can hide - or reveal - a multitude of sins:

Obviously with the armour going on, a heap of holes in the turret were superfluous:

The "basic building blocks" now sound, I set to work adding some details ... the dozer is a nifty little "kit within a kit" which I eventually glued solid into the raised position, although I am looking for another reason to build another of these - it was fun!:
I was agonising over exactly where the mount was positioned on the front, but then I figured it it was attached to the tow points, so I removed the shackles and had the perfect positioners in place:

There were a few little blemishes to fill, bit nothing serious - I opted to set the blade in place because the moulded plastic shafts looked a tad flimsy, but I would like to build another blade with brass rod attachments:


Got a coat of Mr Surfacer on the turret and the start of some reactive armour in place ... not the vacant space on the left rear fender for a scratch built hydraulic unit:

Next challenge will be how the front plate armour was configured - the stock part just don't fit!:
