I thought the bellhousing cert was 2 years. must of been thinking about seat belts. the block plate is correct just used,
For regular steel scattershields, the SFI tag is good for 5 years, as Dale stated. However, if it has a removable "window" panel, those require a re-cert every 2 years.
Just curious if this is the earlier design with the smaller lower bolts holding the bellhousing and block plate together, or the later version that has much larger lower bolts, as well as a curved steel reinforcement plate welded to the upper flange area , where the upper 4 bellhousing bolts go thru. If I remember correctly, the lower bolts on the early version have a 9/16" bolt head, and the later is 3/4", I believe. I have both styles, and I believe that they both use the same part number.
