Help does anyone have (LMC track pattern questions)

I need the layout for the holes so i can have them punched out in the belting for 4 inch center symetical tracks for a LMC 3700C thanks or leads 209-304-5078 email anyandallbuilders@yahoo.com

Are you sure you need 4 inch center holes. The 2100 used 4 inch, but most 3700 tracks I've seen use 4.5 inch centers. I have a set of symmetrical tracks off of a 3700b. What pattern are you looking for? You certainly need to match the grousers you have.

Do you still require this info.

Did you get the pattern you needed? I don't need anything for my projects, I was questioning your track bolt pattern as to whether it was the 4" or 4.5".

I was asking any and all builders...

I don't have a template for the holes. I know that I just parted out a 3700B and it had a mixture of grousers, alignment brackets, and backing plates,. Some were 7/16 and some were 1/2 inch diameter. I drilled out all of the 7/16 and now have uniform 1/2 hole and bolts. It had the larger sprockets, which end up wit 4 1/2 spacing. Maybe the smaller sprocket is the same as the 2100 with 4 inch spacing.
