Hello caragan 1970,
The stock track on the Panzer is 2 inches wide,the plastic Tiger track is 1 3/4 inches wide.The tiger track still looks right on the panzer,and it is very flexable and easy to add or subtract links for length addjustment.Also the exsisting road wheels on the Panzer work just fine after reducing the width by 1/4 inch.One of the problems though,it takes (2) sets of Tiger tracks (total of four)
to do the up-grade.There will be some left-overs from the two sets.In addition you will need the matching sprockets.

Just a note at this point===For me It is less exspensive to buy two new tiger tanks and strip them for all the parts I need to up-grade the Panzer.(less than $150.00 dollars)I end up with two of everything,(4) tracks,(2) radios,(2) sets of boards(4) gear boxes,
(2) guns and gun motors,gun elevation motors,smoker units,gun traverse motors,sprockets,idlers,and all the road wheels.In addition to all the various lights and other internal components.
Not knowing your situation or cost for tanks and or parts,It may be cost efficient for you to go through (Mato in canada).The reason I mention them is the fact that I do know they sell most of the HL parts.(this is just for general information).

At this time I thought a little clarification might be help-full.===For those who may read this the first re-build I did on the Panzer
posted back a few months,I was very happy with and it works just like a typical HL tank.But one of my main concerns was how well the HL boards would hold up under heavy use,or being run on rougher surfaces.(I run mine around the house,or on nice smooth cement surfaces and have run a couple of them on nice fine gravel)
This project that is now under-way on the second Panzer is going to get two sets of gear boxes,two in the front and two in the back.
My plans on how I'm doing this is in theory only and has not been tested by me yet.I "think" it will work the way I plan on doing it,time will tell.The control and duel boards was not bench tested(should have probbly done this but didn't)so this may or may not work out like I plan.The results will be posted good or bad.
Thanks for reading,hope it can be help-full to others---BIGMIG
