This information is from HD Tech Tip #34 and #37.
HD Tech Tip #34 incorrectly listed the part numbers for the two new retro oil tank kits as 62472-93, and 62473-93.
Just correcting the records, the correct part numbers are listed in Tech Tip #37 and shown below.

There were two retrofit oil tank kits available for earlier Sportster models. The oil tank will retrofit to all 1982 to 1993 Sportster models, except the XR-1000.
All earlier tanks were obsoleted and replaced with these two kits.

Corrected part numbers per TT-37:

• 1982-E1987 (62482-93) with flared brake lines.
• L1987-1993 (62472-93) with banjo brake lines.

Later, the kit was updated with new part numbers. ( Click Here to download Instruction Sheet #J00572)
