Replacement leaf spring perches?
 

Doing a 14B LD swap in my truck eventually, gathering parts right now. I want to torch off the taller perches and weld on a new set of the standard height units like my current 10 bolt has.

Wondering if something like this might work? https://www.generalspringkc.com/product_p/250.htm

Or if someone has a better source for something that works better. Hoping 1fastbrick will chime in, he seems to have the most experience with this swap/conversion.

They will probably work.
I used some from summit racing. The ones I used look like the Allstar Performance ALL56126

I had to open the axle housing notch to fit the 14 bolt's larger tubes.

These were made to fit 14b axles. I have nothing to do with the company, just a quick google search for rock crawler spring perches.

I run the ruffstuff specialties ones on my 14ff.
