I read your write up on a speedy-sleeve. I used my digital caliber. Unfortunately, it is so precise that in my clumsy hands I kept coming up with different readings every time I used it. Now a full 1 3/8" would be 1.375. My readings ranged from 1.359 to 1.371. Most of the readings were around 1.362 to 1.364. I assuming I should go with a 1 3/8" Speedi-Sleeve. What do you think?
A rubber seal I can get a local car parts place. They have it in stock. I do not know about the Speedi-Sleeve, but with the information you provided, perhaps they can order it. Thanks much.
