I’m afraid the link won’t open for me.
As for mine; ‘59 Chevy Apache 3/4 ton w/’62 327 cid motor and fully enclosed steel utility box.
‘93 Subaru wagon (little POC but runs good, decent mileage)
Basket case ‘49 1/2 ton Chevy (makes three vehicles if I got around to bolting it back together)
Like that second post said, didn’t realize the link wouldn’t work till I posted.
The 93 may still have a computer. The others are certainly safe but you may need to put an emf cage around your batteries to be sure.
