The T19 was based on the half-track M3, and was set up much like the 75mm GMC M3, with the cab roof removed and the windshield cover folding forward over the hood. The T2 mount involved using parts of the howitzer carriage M2, but incorporated some redesigns to spread the recoil force over a larger area. Nonetheless, the half-track's frame had to be strengthened to prevent sagging. A howitzer shield was fitted, and this was hinged in the middle to present a lower height when not in use. Early vehicles retained the large fender-mounted headlights.
