1987 Supra Comp Single Axle Trailer_Question

Hi all, I just bought a 1987 Supra Comp and have worked out all the kinks other than a bend trailer axle. I have search for a few days on this forum to be sure i didn't miss it but can anyone provide the replacement axle measurements for the axle on the single axle trailer?

There are a few options out there as far as replacements but I need to narrow the size. It appears to be a 4inch - ish drop from center of spindle to top of box tubing. I would like to find the actual factory spec on this axle to ensure I get it correct. Most places have a no return policy in that they have to fabricate a few things on the axle itself.

Any help would be appreciated! Thanks in advance!

I have a 92 SMP I could measure but I don't know if it is the same?

I have the exact boat I could help you out in return if you could send some pictures of your engine harness pm me for email
