Lower end???

MX455:
Hi everyone. I got a 87 K5, I went to do a top end on it and I found the lower end is loose and doesn't feel very good. So i'm going to do a ful rebuild. My question is will the 88 rod fit, or do I need to get the 87. I ask this because I can't get an 87 topend, which is fine because the 88 piston will work. But the wrist pin bearings are different. The other question i have is when i have the crank pressed, it needs to be balanced, right? And if so could any mod shop do this or should I send it some where. Thanks again for everyones help with all my questions.

stewart:
yes the 88 rod fits

MX455:
Thanks for the quick response! :-D

hughes:
I used and 88 rod kit and piston kit in my 87 with great results.

MX455:
Hughes, what company did you get the rod kit from? Does it include the main bearings and seals as well?
