    I've been searching for a first and second gen crossmember comparison picture but no luck. If anyone here has a picture of the crossmembers side to side and driveshaft side to side from 1st and second gen please post a picture. Meantime, I took off dual master and definitely plenty room to try and move the radiator further up a bit. That would now bring me into the dilemma of beginning another project (hydroboost, figuring out hoses, fabing up a mounting bracket, and figuring out an extended push rod. I was hoping that would be down the line.

    found a second gen crossmember in the corner of my garage. not really a side by side comparison but first gen swings forward a good bit, second gen almost flat with motor mount in line with front bolt. Click image for larger version.

ID:	40285 you can see in this pic how the first gen crossmember is twisted to move everything forward. not sure how much and aint taking it off for a pic. my motor mount pillars were cut and fabbed new ones for small block mounts and the new location of 292 passenger mount. regardless, second gen crossmember sets it back farther.

    Thanks for sharing the difference. Would definitely be nice to have a 2nd gen crossmember in my stash. So is the driveshaft on a second gen slightly shorter?

    I'm using a hydroboost out of a 90s Astro van. The mounting bracket was slanted so I believe it was from a 97. 95 and prior years used the flat bracket I believe, which is the ideal bracket. I went back for a flat bracket when I had a chance. I ordered a 3 piece seal kit to replace seals inside. I opened up the hydrobooster even though new seals aren't here yet so I could a get better access to the hydroboost pushrod. For this install I will need a longer pushrod and create a 90 degree bracket to install hydrobooster to the frame rail. Before opening it up I cut the the pushrod in two pieces and I began using a die to create threads to add coupling nuts and create an extension. You don't have to open it up to make threads on the rod. I had it on a vice but due to the clearance from how my vice is mounted it was a daunting task...so I opened it up to see. A lot of sensitive items attached to the rod. We'll see how this goes....

    I forgot I even had the crossmember. driveshaft is from a 108 so too long. shipping would be high from 16063 and would pay it again on your shaft. ask mark or someone on the west coast and if you cant find them both, I will send mine.
