This is old, but I wanted to give my $0.02...if you can't find or afford a UE VBS, the following are your best options in my opinion (in order of best first):

[1] GA 7075-T6 Bulkheads & Braces with UE/Ofna 8-Spider Diffs inside UE Ultralite Diff Cases.
[2] GA 6061-T6 Bulkheads & Braces with UE/Ofna 8-Spider Diffs inside UE Ultralite Diff Cases.

[3] GA 7075-T6 Bulkheads & Braces with UE/Ofna 6-Spider Diffs inside UE Ultralite Diff Cases.
[4] GA 6061-T6 Bulkheads & Braces with UE/Ofna 6-Spider Diffs inside UE Ultralite Diff Cases.

[5] ACNCM 6061-T6 Bulkheads & GA Braces with UE/Ofna 8-Spider Diffs inside UE Ultralite Diff Cases.
[6] ACNCM 6061-T6 Bulkheads & GA Braces with UE/Ofna 6-Spider Diffs inside UE Ultralite Diff Cases.

[7] FLM 6061-T6 Bulkheads & Braces with UE/Ofna 8-Spider Diffs inside UE Ultralite Diff Cases.
[8] FLM 6061-T6 Bulkheads & Braces with UE/Ofna 6-Spider Diffs inside UE Ultralite Diff Cases.

[9] Hardcore Racing 6061-T6 Bulkheads & Braces with UE/Ofna 8-Spider Diffs inside UE Ultralite Diff Cases.
[10] Hardcore Racing 6061-T6 Bulkheads & Braces with UE/Ofna 6-Spider Diffs inside UE Ultralite Diff Cases.

[11] Traxxas 6061-T6 Bulkheads & Braces with UE/Ofna 8-Spider Diffs inside UE Ultralite Diff Cases.
[12] Traxxas 6061-T6 Bulkheads & Braces with UE/Ofna 6-Spider Diffs inside UE Ultralite Diff Cases.

You can still buy the new complete UE 8-Spider/Ultralite and UE 6-Spider/Ultralite kits from the UE Store, but you will need to find the GA bulks on eBay. The 7075-T6 GA Bulkheads are the best bulks ever made, so spending a little time finding them is well worth it.
