Oil Level Indicators 1958-1966 352-390-428

Post by Alan H. Tast » Thu Sep 22, 2016 1:17 am

Questions come up time and again about dipstick length. Did the car have A/C or not? A longer oil level indicator/tube was used on cars with A/C to clear the compressor/bracket for '62-'66s. As for dipstick width, I'm running into an issue as I need to find a dipstick for my '63 Roadster with A/C - replacements I've tried are too wide and bind up in the tube, and I haven't taken time to research part numbers/dimensions yet. The following part numbers show up just for T-birds: would appreciate it if people can add information to this thread to document what's out there.

(6750 is the basic number for the oil level indicator, 6754 is the basic number for the oil level indicator tube)

From Master Parts Catalog FD-7635, Dec 1960, Sec. 66, pp. 16-17 :

C1SE 6750-A - '61 T-bird 390 - 21.92" from shield to Full mark; 23.14" from shield to Add mark; 24.50" from shield to end

Follow-up: Checked replacement tube-type handled indicator I purchased in 1982 from Ford against broken indicator in my '63 Roadster, along with another one on hand with a riveted flat-blade handle that was the same length, and came up with following measurements:

#1 - Handle - Tube style; blade 3/16" wide with wavy upper end to center in tube, blade pressed into tube end, shield crimped onto tube;
Length - shield to Full mark - 23.75"; shield to Add mark - 25.625" (approximate), shield-end, 27.00" (approximate);

#2 & #3 - Handle - Flat, riveted to blade with split/raised portion between shield and rivets to center in tube, shield held in place with deformed tangs ; blade 1/4" wide, straight, blade riveted to handle; Length - shield to Full mark - 24.00"; shield to Add mark - 25.625"; shield-end, 27.00" (approximate)

If you're finding indicators wider than 1/4" they won't work well in OEM tubes. The 1/4"-wide indicators are a little tight. Need measurements of blade widths for '58-'60 indicators.
