Thanks to some help, I've gotten my front end on my '81 sorted out. With some generic ebay shocks and a front damper from SP Takegawa (https://japan.webike.net/products/20223868.html), the front end bobs way less and doesn't bottom out. Now I'd like to make similar improvements to the rear. Has anyone upgraded rear shocks on their Passport? Of the two options I've looked at are again SP Takegawa parts (https://japan.webike.net/products/21594351.html) but the shipping to the US is 115% of the actual price! The other would be some random generics off ebay. Any recommendations for those (with or without reservoirs)?
