The side cover is from a 53 or later 235
because it has the dimple in the center.

1950 thru 1953 - ALL w/ 216 only
9 1/2 x 26 7/8 overall (some list 9 7/16 x 26 7/8)

Begining in 1950 thru 1952
ALL 235
5 5/8 x 27 overall (some list 5 19/32 x 27)

Then in 1953
ALL 235, 261
same as above 5 5/8 x 27
but has the dimple in the center

The coil is located between 3 & 4,
some coils are between 4 & 5.
Anyone know the year difference?
