He recommends welding them. It may not be necessary. The fit is very tight. I suspect locktite would be fine. I say this because the stock spindle nut is retained.

I have the stub for s1/2 and s3 if you guys with machinest skills want to duplicate them.

I'll help however I can.

You'll notice my pics have the part number for the bearings also. Common stuff, cheap and literally twice as big as stock.

 

This sounds weird but... I feel better about going "inspired by" rather than "I copied this"; besides I had something else in mind for hubs. Thank you for the pictures though.

 

Cool, inspired is what i meant. I still haven’t gotten around to installing them if more pictures are desirable. The items are pretty nice.

 

I'm good; just to confirm from the pictures, those are L68149 and LM102949 right? The L68149 is hard to read but process of elimination says that's probably right.

 

Yah it's really hard to tell on both bearings in have but I believe you are correct.

 

S3 on left vs s1/2 on right

 

Going to sell these anyone is interested.

MSF Racing, Marcus and I have have conducted many 1st GEN RX-7 custom parts business over the years, as I have purchased most of his FB RX-7 custom parts product line. Never had I experienced anything negative, you just have to be very patient as he's a one man show and has aging parents he tends too.
