Additional Information

 

* Flanges described with red thickness dimensions and also marked with an asterisk are about 5/16" thick.  All others are about 1/4" thick.  Flanges are made from Mild Steel - Stainless Steel not available.

   

** The measurements - Adjacent Bolt Hole Spacing - is the centerline distance between any two bolt holes (it is NOT the bolt circle of the flange).  Use this measurement if you are trying to match our flanges to existing flanges.  Where there is a range of measurements, this is due to a flange having slotted bolt holes and represents the extremes of having the listed size bolts in the closest locations as well as in the farthest locations.

   

The top three flanges and the 1 5/8" 3 bolt flange (60 D 33) are often used in 1300-1600cc VW headers.

 

The last two numbers in each flange part number represent a particular outside shape. 

For example:  The 2" and 2 1/4" tube flanges share the same last two digits (35) and are an exact match on the outside - only the center hole diameter is different.  If, for some reason, you need to bolt two different tube sizes together, you might be able to do so with some of the above flanges.

 

Blocking Plates are made from Mild Steel - Stainless Steel not available.

Blocking Plates are just Flanges without the center hole and are available to match most (but not all) of the Flanges.  Approximate plate thickness is 1/4" except for 65 T 32 (5/16").

To make ordering or parts matching easier, note that Blocking Plate part numbers are identical to Flange part numbers except the second digit is changed from zero (0) to five (5). 

For example: A 3" three bolt Collector Flange's part number is 60 P 39. The matching Blocking Plate's part number is 65 P 39.

 

Tube and Collector Gaskets match the Flanges and Blocking Plates listed above.  To make ordering or parts matching easier, note that Gasket part numbers are identical to Flange part numbers except that the second digit is changed from zero (0) to eight (8). 

For example:  A 2" three bolt Tube Flange's part number is 60 G 35. The matching Gasket's part number is 68 G 35.
