Did 26/27 frame have gas tank bracket holes?

[signsup]

Working on this former depot hack project that was represented as 26/27 and has those years engine in it. But reading thread on gas filter reminded me that a car of that period would have the tank in the cowl. But this frame has the two holes on one side and one hole on the other for the round tank under the drivers seat.
Do I have a different year frame? Or, were the frames drilled for the gas tank brackets even though the tank would have been under the cowl?

Fordor sedans still had the oval tank under the seat so the frames still had holes for that tank thru the end of production. Chassis also had the oval tank.

If you are unsure of the year of the frame post some pictures and let the experts weigh in. Front and rear crossmembers will help ID it.

Quick check for a 26-7 frame; the running board brackets each have 3 holes.

I believe the pre-1926 gas tank mounting holes on the frame remained into the 1926-27 models. I see them on my two 1926-27 frames. Remember, Ford still offered a chassis, as shown in the picture below.

1909-1910
Short rear cross-member with forged brackets for body and fender support. Painted body color.

1910-1913
Same as 1909, painted body color until sometime in 1910, then painted black thereafter. (Date unknown.) After 1910 the rear body support was a separate forging and no longer a part of the rear fender iron.

1913-1920
Initially the same as the 1911 chassis. About January 1913 two additional rear body brackets were added for the Touring body, under the rear door ahead of the rear seat. These brackets were used only in 1913 and only on the Touring bodies.
Longer rear cross-member, beginning about 271,425 (May 1913), eliminating the forged body brackets. Early rear cross-members were relatively flat across the top surface; not raised as in the later versions. While using the same parts, holes were added for the new front body brackets in mid-1916, and for the battery bracket, starter switch, and battery cable support beginning in 1919. Beginning about March 19, 1919, the “Ford” logo began to be imprinted on the front cross member.

1921-1925
Same as earlier but pressed-steel running board brackets replaced the riveted-in-place forgings used earlier. The holes used for the forged brackets continued at least until 1923. Beginning in June 1920 the front cross-member was made of heavier steel. During 1925 the brake lever quadrant was modified. Instead of four rivets holding it to the frame, only two were now used. This new quadrant continued until the end of Model T production in 1927.

1926-1927
Rear cross-member much longer to accommodate new body and fenders. The rear cross-member was a simple pressed channel in early production, then was made with a stronger flanged design. In early calendar 1926 heavier steel was used for increased strength. A letter to chassis suppliers, dated February 28, 1926, specified the metal to be the same as the truck chassis (Type “L” steel, .180-.200 inches thick). The front cross-member had added brackets to support the fenders.

Thanks for all the great info. It appears that I have a 26/27 frame, although the tank and brackets are round, that is what was on the depot hack when I got it and I will frame my ambulance body around it.
Thanks for confirming.
