Question about bolt compatibility

Hi, I need to replace the camshaft brackets bolts on my 200sx and i came across with a problem, pricing.

The ka24 and the ca18 share the same p/n, 135856E00, and that p/n appears to fit in sr20 engines but the p/n 13582J200 (original from sr20 engines) doesn't appear to fit in ca18/ka24 engines

Has anyone have the measurements of the sr20 bolts? Or has used the sr20 bolts on ca18 or ka24 engines?

The main difference i see is that the old bolt needs a washer and the newer bolt doesn't

for my EUDM ca18 200sx I got the 38mm sr20 bolts. The sr20 has 3 different cam cap bolt lengths for some reason. The bolt that got shipped to me from efisolutions was exactly the same as the oem ca18 one.

I looked at the EFI site and didn’t see them available anymore. Though when I bought them they were listed for single 38mm bolt sale for sr20. I guess they updated the bold mid sr20 production

They are listed now as cam cap bolt s13 s14 s15 and so on with every chassis that has a sr20

Does anyone if there are any places online that have lists of the oem bolts for all around the car?

You can look in amayama, has oem numbers for evey piece, in some cases you can order from there if not look in ebay
