Several years back I purchased used a SPL Rear Lower Control Arm and a NIB SPL Toe Arm from a Dallas Twin fan transitioning out of the community.
I emailed SPL requesting help finding a STX legal rod end. Help came with a link to Steinjager products, specifically their 5/8-18 RH Male Poly Bushing, 0.5” x 1.5” (p/n J0012131).
Find the part here:

My SPL LCA is a first-generation design, but this rod end conversion works the same with the latest generation LCA (p/n SPL RLL FRS).

Note picture with OEM LCA on left and Steinjafer.com poly rod end on the right. The amount of metal in the Steinjager unit meets the STX rules requirement that the metal/non-metallic component ratio on the replacing rod end does not exceed the metal/non-metallic component ratio in the OEM rod end. (See SCCA Solo 14.8B)
The rod end is available in either zinc plating and black gloss powder coat. I bought the black power coat for a MSRP of $25.87 plus shipping (black powder coat is about $3.00 more than zinc version).
The same rod end fits the SPL Toe Arm w/lockout (p/n SPL TRAEL FRS) and should, but not verified, the Traction Arms (p/n SPL RTR FRS).
The Steingjager is 1.5” wide with a 12.7mm (1/2”) bore. The OEM bushing is ~2.5mm wider and uses a 12mm bore. I used two, ½” flat 1” diameter washers to take up the side-to-side play (one on each side of the rod end) lubed with AMSOIL #2 Lithium HD Synthetic Grease. I treated all metal components and hardware with AMSOIL MPHD Metal Protector before assembly.
Buy the SPL Adjustment Wrench. Original Purchaser of my LCA did not and he buggered the anodized locking nut enough to annoy.
When assembling the poly rod end leave ¾” or so of threads exposed from rod end weld to locking nut to better clear the under car mounting bracket flange. Also orientate the blue, 3/16” Allen head bolt of the locking clamp downward (opposite of what is shown in mock-up assembly picture).
Measured the OEM LCA finding center-to-center at 17 11/16.” I set the SPL LCA at 17 7/8” to get me close enough to drive to Growler Motor Labs Plano TX for an alignment.
Steinjager will manufacture a metric rod end that matches the OEM dimensions for a minimum buy of 30 units. If enough interest is generated I would be willing to either coordinate a group buy, see if SPL has an interest in supplying, or find an approved FT86 Club vendor who wishes to add the metric sized rod end to their product line.
