I would measure the barrell ID as well.

For sealant use Dow Corning 732, $12.00 on Amazon. Wet your index finger and lightly smooth the sealant.. Allow 24hrs to fully cure before mounting tires.

Good luck!

yea I plan on doing it myself.. I did it before just more interested in who makes good lips and barrels ya know

Ive used american rim supply barrels before and http://www.amcrimhalves.com/Rim-Halves/ , they claim they get their supply from triangle hard alloys who are a supplier to hre.

This place offers stainless barrels which will give you a better shine and easier to maintain finish than aluminum but with added weight and cost

AMC rim halves are all Triangle product, that is true, and they are decent quality. The other option is ARS rim halves in San Diego, who supply HRE and Forgeline, as well as many others. AMC is easy to order from because of the way their site is designed. ARS spins them right at their facility but are set up wholesale only.
