I have the small outboard air grabber box to hood seal dimensions and I have the strips of material cut for the large, center section air grabber box to hood seal. But I need to know the outer perimeter length of the large seal.

From the factory it's just a long strip that's butt spliced (on a 45 dregee angle) to form a large circular shape. I used to know the dimension. From memory I thought it was 54" I know it's not terribly critical. +/- .25-.5" is probably fine.

Anyone have box handy the can use a seamstress tape or piece of string (something very flexible and accurate) to measure the perimiter of a seal on a box. Would obviously have to be a box thats not mounted.
