Dresser TD 8E

We recently bought this dozer cause the TD15 is too big. Looks great new paint decals etc. but the bottom
is toast. I have looked all over this computor nobody even lists pins & bushings, then back in my day they
would press these on site. Idea maybe we will cut some pipe and weld two halfs together, better then nothing
Yes new chains available can't afford that now. tough winter we don't get spring till June here in Masshole
any ideas ? sam
