A question. To those of you that have done the front crossmember swap, what 2 holes did you have to drill? Where are they located? I am planning on this swap in about a month or so. I wanna make some measurments, because, I also want to convert to the 73 and up engine mount system so I can get a polyurathaine engine mount set-up. I basicly wanna measure the way the engine sits in the 69 now, and the way my engine sits in my daily driver 86.

But if someone can let me know what holes are drilled so I can take soild measurments that would be great. Also, how far off from the other holes did you have to drill? Thanks for any help.

if i remember correctly you need to oblong the front top on the side of the frame and drill the rear top on the side as well, or vice versa hard to remember 8 months ago
