Valvebounce Posted November 3, 2014 Report Share Posted November 3, 2014 I need to know asap how thick the rubber mounts are that sit between the radiator support panel/inner fenders, and the chassis at the front of the truck. Including the washers too I suppose. My unbelievably rust free (but crashed) 620 is about to have a new donor front grafted on at the firewall. And I'm going to turn up some temporary solid spacers to get the new front at the correct height for the marriage to take place. Also, what size and length are the bolts which hold this joining together? (Just the very front two mounts) Quote Link to comment

datzenmike Posted November 3, 2014 Report Share Posted November 3, 2014 The mounting rubber doesn't determine the correct height or alignment for the rad support to the cab. For one the rubber compresses when tightened down. I would line it up by eye and some measurements. I put a 4" lift on my cab and had to trim the spacers to fit, or when tightened down, the fender gap to door and hood gap to cowl would change. Quote Link to comment
Charlie69 Posted November 4, 2014 Report Share Posted November 4, 2014 Stock body mount bolts are shouldered to prevent over tightening. This also maintains the height of the cab. Quote Link to comment
datzenmike Posted November 4, 2014 Report Share Posted November 4, 2014 Like the metal sleeve in a shock absorber. Right. Quote Link to comment
Valvebounce Posted November 4, 2014 Author Report Share Posted November 4, 2014 I still need a ball park figure as we're going to be re spotting the inner guards onto the firewall. If this part isn't pretty close, then the whole truck would wind up quite out of whack. if I know roughly how thick they're supposed to be, then we've got a fighting chance of getting the face which the front fenders (we call them mudguards down here) attach to parallel to the chassis rails. Since the cab did get a smack, it might be required to knock parts of the mating face on the firewall forward to meet the inner fenders. There are many variables......... Quote Link to comment
Charlie69 Posted November 7, 2014 Report Share Posted November 7, 2014 Here is what I came up with a few years ago. I used this combination on my 520 wit only one change the 2 body to frame bolts had to be longer under the radiator core support. These are a combination of 620 and 720 bushings.

orangie Posted November 19, 2014 Report Share Posted November 19, 2014 My replacement ones are about 3/4 of an inch.. They're not rubber, but polyurethane instead, so they hardly compress. I think they were for a jeep. Quote Link to comment
red13 Posted November 19, 2014 Report Share Posted November 19, 2014 I heard hockey pucks work Quote Link to comment
sebpv Posted November 22, 2014 Report Share Posted November 22, 2014 thats what i did. Used the old old rubbers for thickness and diameter then made circular bushings using a drill fixture. I cant remember the sizes tho. Best to match them inside tbe chassis cups for best result. Quote Link to comment
datzenmike Posted November 22, 2014 Report Share Posted November 22, 2014 Stiffer material will transmit vibration. If poly or hockey pucks they might as well be made of aluminum. This is the cab not a suspension part. Rubber! Quote Link to comment
