I'm replacing the exhaust manifold gaskets on my 88 classic and I can't get some bolts to go in straight. The two closest to the firewall go in straight, the two forward of those two are slightly off line, the next two are straight, and the two closest to the front of the vehicle are slightly off line. I could probably get them in, but am wondering if this is not a good idea. If not, then what do I do. When I was taking some of the bolts off, I noticed that some came off not completely straight out. The threads were a little trashed. Any advice.
Thanks,
Doug
