I am going to do a bit more work tonight. I have shaved off the fireextinguisher "block" on the top glasis slope on the A2.I will put the M-48 box here.
ALSO...remove the fuel filler cap on the left side of the hull,near the turret ring.Diesels only had one on the right side.
On my tank,we did not have those tie down things on the rear fenders.I shaved them off.

Also,I plan on drilling the lightening holes on the various fender support braces.
And I have grooved in between the center driver's periscope,and the 2 on either side,this is a rain water run off channel.

Later,I will close the center periscope hatch,and use parts from the M-48,to "open" the periscope covers on either side.We ran this way,so the driver could see the ground guide easier while maneuvering in the motor pool.
And I drilled out the crew heater exhaust pipe.This did have a plastic cap that fit into it,and was rapidly lost in the "bush".
I will add pictures to this post,so you can see what I am typing about,but fisrt I got to do the cutting.
